It isidentical with IEC 60079-7:2015. It supersedes BS EN 60079-7:2007, which iswithdrawn. It partia

2、lly supersedes BS EN 60079-15:2010, specifically therequirements for Type of Protection “nA”.The significance of the changes between this standard (for “ec”) and BSEN 60079-15:2010 (for “nA”) are listed in a table in Annex ZY. The majortechnical changes include:- Soldered Connections- Thermal stabil
