Sets out requirements for the classification of Class II hazardous areas according to the existence of, or the likelihood for the existence of, electrically conductive or non-conductive combustible dusts. Appendices cover basic dust-hazard principles, and tables are given of the important characteristics of agricultural, carbonaceous, chemical, metal and plastics dusts.

This standard sets out requirements for the classification of hazardous areas according to the existence of, or the likelihood for the existence of, combustible dusts. Such areas are referred to as Class II areas.The standard applies to open and enclosed areas where ambient air temperature and pressure apply. Areas where higher and lower atmospheric temperatures and pressures are present are not excluded provided that their effects on the properties of the flammable materials are taken into account. 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.NOTES:1. Appendix A gives information on the basic principles of dust hazards.2. Appendix B contains data on various dusts.3. Explosive gas atmospheres covered by AS 2430, Part 1, are referred to as Class I areas.
