Explosive atmospheres, Part 20.1: Material characteristics for gas and vapour classification – Test methods and data (ISO/IEC 80079-20-1:2017, (ED. 1.0)/COR1:2018, MOD)
The objective of this Standard is to provide guidance on classification of gases and vapours. It describes a test method intended for the measurement of the maximum experimental safe gaps (MESG) for gasair mixtures or vapour-air mixtures under normal conditions of temperature and pressure (20 °C, 101,3kPa) so as to permit the selection of an appropriate group of equipment.
