3 Equipment General requirements issued by the InternationalElectrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on therecommendation of the Electrical apparatus for explosive Atmospheres Sectional Committee andapproval of the Electrotechnical Division standard was first issued in 2007 and was identical to IEC 60079-0 : 2004 (Edition ). Thisfirst revision has been undertaken to align it with IEC 60079-0 : 2007 (Edition ).The significant changes with respect to IS/IEC 60079-0 : 2004 are listed below:a) Requirements for explosive dust atmospheres transferred from IEC ) The marking Group II alone has been replaced by IIA , IIB , or IIC as many of the enclosurerequirements are now aligned with a specific ) dust groups defined as Group IIIA, IIIB and ) Limits for ultrasonic and electromagnetic radiation ) Remainder of electrostatic requirements transferred from IEC )Equipment protection levels (EPL) ) Transition of term from apparatus to equipment (where appropriate).

4 The text of IEC Standard has been approved as suitable for publication as an Indian Standard withoutdeviations. Certain conventions are, however, not identical to those used in Indian Standards. Attentionis particularly drawn to the following:a) Wherever the words International Standard appear referring to this standard, they shouldbe read as Indian Standard .b) Comma (,) has been used as a decimal marker while in Indian Standards, the currentpractice is to use a point (.) as the decimal this adopted standard, reference appears to certain International Standards for which IndianStandards also exist.
