8. TEST #ETHOS

7.1. Distortion at 5r%-%ut a test specimen 5 b =";mm substantiall flat and strai#ht ith the=";-mmdimension parallel to the machine direction of the strip. %lamp the specimen beteen

to bloc&s so that the expansion joint forms a cantilever of :-mm len#th. !lace the clamp and

joint assembl in a force-draft oven maintained at 52 =. 1>%ith the specimen in a hori?ontal

position for to hours. Measure the deflection of the specimen from the hori?ontal.

8.2. Bri#leness$Cs%i a test specimen 5 b =";mm ith the 15-mmdimension parallel to the

machine direction of the strip. Maintain the specimen at a temperature of * to +>% in ater for at

least to hours prior 1 testin#. %lamp the specimen beteen to boards so that the expansion

joint forms a cantilever of :-mm len#th and holds in a hori?ontal position b a suitable ri#id

support. "uspend a spherical cast iron ball ei#hin# * # and havin# a diameter of *7 mm b a

cord tied to an eelet fastened to the ball. )or specimens havin# a thic&ness of 1* mm or less

suspend the ball 3 mm above the center of the projectin# portion of the specimen. )or

specimens over 1* mm in thic&ness suspend the ball + nun above the specimen. $elease the

ball b burnin# the cord above the eelet. ;ther suitable suspension and release devices ma be

used.

8.3. WaterAbsorplion-C#t a test specimen 5 b 15 mm from the joint filler material in such amanner that all ed#es are freshl cut and determine the mass. =mmerse the specimen in ater

for

2* hours remove and ipe off the surface ater ith a sli#htl dampened cloth. Measure the

mass of the specimen 8uic&l and calculate the #ain in mass and express as mass percent of

ater absorbed.

8.4. Compression-Test the joint filler in accordance ith "ections ,.2 to ,.2.5 ofT *2 except ma&eonl a sin#le application of the load re8uired to compress the specimen to 5 percent of its

thic&ness before test@ and do not measure the recover.

-ote 5--The distortion and brittleness tests are used to determine the handlin# characteristic ofthe material. The ater absorption and compression tests are /ed to determine the suitabilit of

the material as an expansion joint filler.

7.5. &re!ision and Bias:

7.5.1. !recision statement for sin#le operator as calculated per A"TM % +, Table 2 maximumacceptable ran#e of individual measurements. o precision statement is necessar for brittleness

since this propert is 8ualified as an attribute. !recision statements are listed in Table 1.

8.5.2. "ince there is no accepted reference material suitable for determinin# the bias in this test methodno statement on bias is made.
