FOREWORD”

‘1’11is Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards, after the draft finalizedby the Fire Fighting Sectional Committee had been approved by the Civil Engineering Division Council.

Dividing breech ing is used by the fire brigades for dividing a single line of hose into two. A good practice is tofit a dividing breeching with control in the hose line even if a single line is to be used. This enables a second lineto be added later, if required. Also, if two lines are in use through a dividing breeching with control, one of thesecan be shut-off, if required.

This standard was first published in 1969 and revised in 1986. This revision has been prepared so as to givespecific dinlcnsions for the various parts changes in materials of components besides updating the requirementsso as to make it in line with related Indian Standards which have been revised.

The composition of the Committee responsible for the formulation of this standard is given at 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 with1S 2: 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.
