FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Fire FightingSectional Committee had been approved by the Civil Engineering Division Council.

This standard permits the use of copper, copper alloys, aluminium and aluminium alloys only in the manufactureof couplings, and it is strongly recommended that all the components be made in either aluminium or its alloys

and copper or its alloys as it is essential to avoid, as far as possible, coupling aluminium alloy to copper alloys

or vice versa, particularly for long periods, or otherwise electrolytic action may result from the close proximity ofthese metals to each other. It is also recommended that aluminium alloy fittings be made from gravity die-castings, unless otherwise approved by the purchaser. On die-cast fittings, where the bore is shown as parallel,it is suggested that the manufacturer be allowed a resonable taper to facilitate core withdrawl but this tapershould be kept to the minimum required for this purpose. Other materials maybe used with the prior approval ofthe purchaser provided that they have good corrosion resistance to all types of water, including sea water orbrackish water, and there is no change of electrolytic action between adjacent materials. It is also essential thataluminium alloy couplings are thoroughly washed with fresh water immediately after use with sea water orbrackish water.

The Composition of the Committee responsible for the formulation of this standard is given in Annex A.

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 withIS 2:1960 ‘Rules for rounding off numerical values (revised)’. The numbers of significant places retained in therounded off value should be the same as that of the specified value in this standard.
