Proposes the adoption of IEC 60079-20:1996, which gives guidance on the selection of appropriate electrical apparatus, protected by flameproof enclosures or designed to be intrinsically safe, according to the gas or vapour in which it is intended to be used, and which provides tables of chemical and engineering properties of substances, to assist electrical engineers in their selection of electrical apparatus. Copies of IEC 60079-20:1996 may be purchased from or viewed at any Standards Australia office or at Standards New Zealand. Proposed as a Joint Australian/New Zealand Standard.
