1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

Accreditation is granted to the facility to perform the following calibrations

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its

fixed location

4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite

at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration

onsite at the customerrsquos location

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both

at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the

laboratory performs this calibration at its fixed location and onsite at customer locations

6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger

than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due

to the effects of transportation of the standards and equipment and upon environmental conditions at the

customer site which are typically not controlled as closely as at the laboratories fixed location

7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of

accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a

more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at

a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty

associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the

same calibration since capability and performance of the device being calibrated and the conditions related to the

calibration may reasonably be expected to deviate from ideal to some degree

2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval

from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The

low end of this range must be an attainable value for which the laboratory has or has access to the standard

referenced Verification of an indicated value of zero in the absence of a standard is common practice in the

procedure for many calibrations but by its definition it does not constitute calibration of zero capacity
