Find your way through this huge site to the Standards and Regulations Department and locate Publications available for download.  In the resulting list you will find a useful booklet on the ATEX Equipment Directive.
 
Now termed the Department for Business Enterprise and Regulatory Reform, (ex DTI) from this page you can download the Directive and the DTI Guide to the Directive in Adobe pdf format.

Standards Association of Australia   Australian standards and product testing

National Fire Protection Association   USA NFPA National Electrical Code NFPA 70.  Article 500 covers hazardous areas. Still valiantly hanging on to the outdated Division concept! (But recognising the IEC as well)
The National Electrical Code (NEC)
The National Electrical Code is the "Bible" of the Electrical Industry, and the primary source of reference for hazardous locations. The NEC is also the basis for OSHA standard, Hazardous (Classified) Locations. There are several OSHA standards that require the installation of electrical wiring and equipment in hazardous (classified) locations according to the requirements of Subpart K, Electrical. The NEC should be consulted as a supplement to the OSHA standards for additional background information concerning hazardous locations.
