Provides guidance on the selection of the appropriate group or subgroup of electrical apparatus, protected by flameproof enclosure or designed to be intrinsically safe, according to the gas or vapour in which it is intended to be used. Provides the basis for the classification of the most used gases and vapours. Guidance is given on the tests to be carried out to classify any additional gases or vapours not listed in this report.
