(Superseding IS 3809 : 1979)

Reaffirmed 2022

NATIONAL FOREWORD

This Indian Standard (Part 7) which is identical with ISO 834-7 : 2000 ‘Fire-resistance tests — Elements of building construction — Part 7: Specific requirements for columns’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Fire-Safety Sectional Committee and approval of the Civil Engineering Division Council.

This standard supersedes IS 3809 : 1979 ‘Fire resistance test of structures (first revision)’. After publication of this standard, it shall be treated as withdrawn. This standard is published in various parts. Other parts in this series are:

Part 1 General requirements

Part 4 Specific requirements for load bearing vertical separating elements

Part 5 Specific requirements for load bearing horizontal separating elements

Part 6 Specific requirements for beams

Part 8 Specific requirements for non-load bearing vertical separating elements

Part 9 Specific requirements for non-load bearing ceiling elements

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are however not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
