Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 84) (Third Revision) which is identical with IEC 60695-4 : 2021 ‘Fire hazard testing - Part 4: Terminology concerning fire tests for electrotechnical products’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Environmental Testing Procedures Sectional Committee and approval of the Electronics and Information Technology Division Council.

This standard was first published in 2001 and subsequently revised in 2008 and 2018. The third revision of this standard has been undertaken to align it with the latest version of IEC 60695-4 : 2021.

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and 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.
