Development of ISO/IEC 80079-41/Ed1: Explosive atmospheres - Part 41: Reciprocating internal combustion engines


To develop an International standard that covers the technical requirements necessary to avoid or minimize the significant hazards, which could occur during normal operation, maintenance or foreseeable malfunction of reciprocating internal combustion engines including

• Group I EPL Mb for use in underground workings susceptible to firedamp and/or combustible dust,
• Group II EPL Gb and Gc for use in potentially explosive atmospheres of flammable gas and vapour and
• Group III EPL Db and Dc for use in potentially explosive atmospheres of combustible dust.
