Indian StandardBRANCH PIPE, UNIVERSAL FOR
FIRE FIGHTING PURPOSE — SPECIFICATION( Second Revision )
ICS 13.220.10
Fire Fighting Sectional Committee, CED 22
FOREWORD
This Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards, after the draftfinalized by the Fire Fighting Sectional Committee had been approved by the Civil Engineering DivisionCouncil.
Branch pipe, universal, is one of the important items of water fittings used for general fire fighting, marine firefighting and for the fire fighting in oil refineries. In addition, branch pipe, universal, is also used for layingdust in mines and for smoke dispersal in rescue operations. The advantages of this type of branch pipe overthe ordinary branch pipe covered by IS 903 : 1993 ‘Specification for fire hose delivery couplings, branch pipe,nozzle and nozzle spanner (fourth revision)’ are that it is capable of providing atomized spray and widespreading curtain in addition to a straight jet and it minimized water damage which is of particular importanceon board ships and in storage rooms. This standard has been formulated with a view to providing guidanceboth in manufacture and purchase of branch pipes, universal, of proper design and construction and capableof giving the required performance.
This standard was first published in 1964 and revised in 1983. This revision has been brought out so as togive complete details of the branches and also keeping its provisions in line with the latest Indian Standardson similar items. Stainless steel has been also incorporated as the material of construction.
The composition of the Committee responsible for the formulation of this standard is given in Annex B.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final valueobserved 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 number of significant places retained inthe rounded off value should be the same as that of specified value in this standard.
