The objective of the IECEx System is to facilitate international trade in equipment and services for use in explosive atmospheres, while maintaining the required level of safety:
Ex areas can be known by different names such as “Hazardous Locations”, “Hazardous Areas” “Explosive Atmospheres”, and the like and relate to areas where flammable liquids, vapours, gases or combustible dusts are likely to occur in quantities sufficient to cause a fire or explosion.
The modern day automation of industry has meant an increased need to use equipment in Ex areas. Such equipment is termed “Ex equipment”
Ex equipment in such areas include:
In addition to the preparation of International Standards, the IEC facilitates the operation of Conformity Assessment Systems. One such System is the IECEx System.
The IECEx System comprises the following:
To assist in a common understanding of the aims, objectives and procedures of the IECEx System, the IECEx Secretariat maintains various guidance documents.
