0. FOREWORD0.1 This Indian Standard ( First Revision ) was adopted by the IndianStandards Institution on 15 March 1974, after the draft finalized by theFire Fighting Sectional Committee had been approved by the CivilEngineering Division Council.0.2 As one of the important items of first-aid fire fighting equipment,fire buckets have t o conform to certain essential requirements in regard toshape, design, construction and finish. This standard has been preparedwith a view to providing guidance both in manufacture and purchase ofgalvanized mild steel fire bucket of proper design and construction. Thisstandard was published in the year 1963. This first revision has beenprepared to incorporate the revised design of bucket as recommended byOrdnance Factory, Dum Dum.0.3 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated,expressing the result of a test or analysis, shall be rounded off in accord-ance with IS : Z-1960*. The number of significant places retained in therounded off value should be the same as that of the specified value in thisstandard.

1. SCOPE1.1 This standard lays down the requirements regarding material, dimen-sions, manufacture, finish and tests of galvanized mild steel fire bucketof 10 litres nominal capacity.2. MATERIAL2.1 Mild Steel Black Sheets- Mild steel black sheets used for themanufacture of buckets shall conform to Grade St 34 or Grade St 42 ofIS : 1079-1968t.
