Explosive Atmospheres - Part 20-1: Material Characteristics for Gas and Vapour Classification - Test Methods and Data
Also Known As:
ISO/IEC 80079-20-1:2017 is a standard that focuses on the material characteristics for gas and vapour classification in explosive atmospheres. It provides guidelines and test methods for the determination of the maximum experimental safe gaps (MESG) and auto-ignition temperature (AIT) of gas-air mixtures or vapour-air mixtures. This allows for the selection of appropriate equipment to be used in hazardous areas.
The standard includes a table in Annex B which provides data on the chemical properties of materials, assisting in the selection process for equipment in hazardous areas. The data in this document is sourced from various references listed in the bibliography.
It is important to note that these test methods can also be applied to gas-air-inert mixtures or vapour-air-inert mixtures, but specific data on air-inert mixtures is not tabulated in this standard.
