What is ATEX?
ATEX stands for Atmosphere EXplosibles. It is a legal framework that businesses must follow in order to protect employees and property from explosion risk in areas with a potentially explosive atmosphere.
Furthermore, ATEX is the term used for European Union’s Directive 94/9/EC which concerns equipment & protective systems intended for use in potentially explosive atmospheres.
The purpose of the directive is to facilitate trade by harmonizing “rules” regarding the safety requirements for the hazardous area products.
For ex-proof products coming to Europe, they require ATEX certification. Information needed in the certification includes the notifying body i.e. IMQ, certification number and the CE marking. CE stands for “Conformité Européene" which literally means "European Conformity”.
IECEx stands for International Electrotechnical Commission Explosive. It is a system used to facilitate international trade in equipment and services for use in explosive atmospheres while maintaining the required level of safety.
IECEx Certificate of Conformity is issued by approved IECEx Certification Bodies (ExCBs).
The purpose of the IECEx Certificate of Conformity attests that a sample of the Ex product described on the Certificate has been independently tested and found to comply with the International (IEC) Standards listed in the certificate. It also attests that the manufacturing site has been audited to verify that the manufacturer’s quality system meets IECEx requirements specified in the IECEx Operational.
Both ATEX and IECEx explosion proof certification standards are based on IEC 60079 standard.
