Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 34) which is identical with ISO/IEC 80079-34 : 2018 ‘Explosive atmospheres — Part 34: Application of quality management systems for Ex Product manufacture’ issued by the International Electrotechnical Commission (IEC) and International Organization for Standardization (ISO) jointly was adopted by the Bureau of Indian Standards on recommendationof the Electrical Apparatus for Explosive Atmospheres Sectional Committee and approval of the Electrotechnical Division Council.

The text of the 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.
