The IECEx System is based on the use of International Standards, such as IEC Standards.

These Standards are dedicated to the industry fields associated with the use of equipment.  This equipment is abbrieviated to the term 'Ex' and is installed and operated in potentially hazardous areas at risk of fire or explosion.

Below is a list showing a selection of the current Australian Standards covering electrical equipment located in Group II and Group III Hazardous Areas. This list was checked against https://infostore.saiglobal.com/store/ on the 16th January 2010.
