Indian Standard HIGH PRESSURE FIRE HOSE DELIVERY COUPLINGS — SPECIFICATION ICS 13.220.1077.150 OBIS 2001 BUREAU OF INDIAN STANDARDS MANAK BHAVAN, 9 BAHADUR SHAH ZAFAR MARG NEW DELHI 110002 December 2001 Price Group 3 Fire Fighting Sectional Committee, CED 22 FOREWORD This Indian Standard was adopted by the Bureau ofIndian Standards, after the draft finalized by the Fire Fighting Sectional Committee had been approved by the Civil Engineering Division Council. This standard permits the use ofcopper, copper alloys, aluminium and aluminium alloys only inthe manufacture of couplings, and itisstrongly recommended that all the components be made ineither 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, orotherwise electrolytic action may result from the close proximity of these 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 taper should be kept tothe minimum required for this purpose. Other materials maybe used with the prior approval of the purchaser provided that they have good corrosion resistance to all types of water, including sea water or brackish water, and there is no change of electrolytic action between adjacent materials. It is also essential that aluminium alloy couplings are thoroughly washed with fresh water immediately after use with sea water or brackish water. The Composition of the Committee responsible for the formulation of this standard is given in Annex A. For the purpose of deciding whether aparticular 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 numbers of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
