Sets out requirements for the selection, installation and maintenance of electrical equipment for use in areas where combustible dust may be present in quantities that are likely to produce a fire or explosion.

This Standard specifies requirements for the selection, installation and maintenance of electrical equipment for use in areas where combustible dust may be present in such quantities as are likely to produce a fire or explosion hazard. Such areas are hereinafter referred to as Class II areas.NOTE: AS 2430.2 deals with the classification of Class II areas.This Standard does not apply to-(a) areas where inherently explosive dusts are present;(b) underground workings of coal mines; and(c) areas which may be affected by oxygen enrichment.
