FOREWORD

This Indian Standard (Part 1) was adopted by the Bureau of Indian Standards, after the draft finalized by the Shipbuilding Sectional Committee had been approved by the Transport Engineering Division Council.

This standard (Part 1) lays down requirements for the drinking water connection for attachment of piping from another ship or from a land distribution system.

Part 2 of this standard covers components of filling connection for drinking water tanks.

In order to achieve harmony with the international practices, this standards is based on IS0 5620-1:1992 Shipbuilding and marine structure - Filling connection for drinking water tanks, Part 1 : General requirement published by international Organization for Standardization.

The requirements of the Statutory Authorities are to be complied with as may be applicable to the individual ship concerned.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2: 1960 Rules for rounding off numerical values (revised). The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

SHIPBUILDING - FILLING CONNECTION FOR DRINKING WATER TANKS

PART 1 GENERAL REQUIREMENTS

1 SCOPE

1.1 This standard (Part 1) specifies the principle requirements, the composition and the designation of the complete filling connection and gives a recommendation for the installation aboard ship.

1.2 Details for the components ofthis filling connection are given in Part 2 of this standard; both for the distribution system and for the ship.

1.3 The general rules for drinking water distribution systems fall within the competence of national port authorities and are outside the scope of this standard.

3 FIELD OF APPLICATION

This connection safeguards drinking water tanks from being filled with any other fluid. Additionally it safeguards the supply piping of the drinking water from contamination by any other liquids.

4 GENERALREQUIREMENTS

4.1 Connection Principle

The connection is carried out by means of special

watering flanges. A flange shall be fitted to the ships piping (flange B) and a second one (flange A) to the piping or hose line from the drinking water supply source at which the ships watering (flange B) shall be provided with a blind (flange C) (see Fig. 1 j.

4.2 Flange Connection

4.2.1 The watering flange A, B and C shall have a special 5 screw connection, according to the dimensions as given in Fig. 2.

4.2.2 The nominal diameter of flanges connection and piping shall be DN 65.

4.2.3 The nominal pressure of flanges connection and piping shall be PN 16.

4.3 Securing of Connection and Main Dimensions

To prevent unauthorised access to the connection on the ship the blind flange C shall be secured by a corrosion-resistant padlock which is fitted to a securing bolt at the lower part of the connection, as shown in Fig. 3.

4.4 Packing

A gasket of Neoprene rubber with suitable hardness be used for drinking water systems and shall be fitted to the ship watering flange B.

4.5 Materials and Finish

4.5.1 The flange connection shall be made ofweldable structural steel conforming to Grade A of IS 2062.

4.5.2 Corrosion protection shall be obtained by hot galvanizing in accordance with IS 4759 or by other approved coating which would not constitute a health hazard.

5 COMJ?OSITION

5.1 Components

The composition (code letter Z) of the ship piping connection shall be as given in Fig. 3 consisting of components as listed in Table 1.
