Because of this. after the draft finalized by the Fire Fighting Sectional Committee had been approved by the Civil Engineering Division Council. . Two types which are mostly used have been covered in this standard. accordance with IS 2 : 1960 ‘Rules for rounding off numerical values ( revised)‘. The landing valves are sometimes also referred to as internal hydrants because these are usually fitted inside the buildings for wet hydrant system. This standard was first published in 1969 and revised subsequently in 1977 and 1983. This revision has been prepared in order to update the provisions of the standard which has been done for incorporating the amendments and modified figures. expressing the result of a test or analysis. the shall be rounded off in The number of sign& specified value in this For the purpose of deciding whether a particular requirement of this standard final value. observed or calculated. Landing valves may be installed in different ways and altitudes and for yielding varying output of water.Fire Fighting Sectional Committee. is complied with. CED 22’ FOREWORD This Indian Standard ( Third Revision ) was adopted by the Bureau of Indian Standards. requiring different shape and sizes. the design of these valves has to be compact so as not to cause any obstruction to the passage where these may be installed. cant places retained in the rounded off value should be the same as that of the standard. from where fire-hose could be laid out by the fire brigade or trained men for fighting fire on the concerned floor. The landing valves when used for sea water should not be made of aluminium alloy. The composition of committee responsible for the preparation of this standard is given in Annex B. The instantaneous female outlets may also be manufactured as a part of landing valves.
