IS/IEC 60079 : Part 5 : 2015 + AMD 1 : 2022 Explosive Atmospheres - Part 5 Equipment Protection by Powder Filling "q"
NATIONAL FOREWORD
This Indian Standard (Part 5) (Second Revision) which is identical to IEC 60079-5 ‘Explosive atmospheres - Part 5: Equipment protection by powder filling "q"’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Electrical Apparatus for Explosive Atmosphere Sectional Committe and approval of the Electrotechnical Division Council.
This standard was first published in 2009 as IS/IEC 60079-5 : 2007 ‘Explosive atmospheres: Part 5 Equipment protection by powder filling ‘‘q’’ and was revised in 2017.
This revision has been undertaken to align it with latest version of IEC 60079-5 : 2015 + AMD 1 : 2022.
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’; and
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.
