IECEx international scheme

IECEx 02 – Device certification scheme

Voluntary certification scheme for IECEx 02 devices allows a manufacturer of equipment for potentially explosive atmospheres to obtain a certificate of conformity accepted in the participating countries for this certification scheme.

Due to certain national regulations, the IECEx certificate does not allow the device to be placed on the market. IECEx certified equipment in this case requires national certification or evaluation. This is particularly the case for countries belonging to the European Union for which an evaluation relating to the ATEX directive must be carried out. However, the evaluation of an IECEx certified product from a non-EU country is greatly simplified since the tests carried out by an Ex Test Laboratory can be used by a Notified Body.

This IECEx certification scheme as well as the various procedures which result from it make up the IECEx voluntary certification reference system. The evaluation reference system includes international Ex standards and various documents available on the IECEx website.

The evaluation of a device takes place in several stages in accordance with the IECEx standard. If successful at all stages, an IECEx certificate of conformity (IECEx CoC – Certificate Of Conformity) is issued.

The issuance of this global certificate of conformity, by a certification body recognized by the IECEx: an ExCB (Ex Certification Body), is carried out on the basis of:

Test and evaluation results of samples attesting to their compliance with the IEC standards which apply to this device. These examinations and tests must be carried out by a laboratory recognized by the IECEx: an ExTL (Ex Testing Laboratory).
Results of the assessment and audit of the manufacturers’ quality system carried out by an ExCB. This audit certifies that the manufacturer manufactures his product under a quality assurance system and that the requirements of the IECEx certification scheme, under the supervision of ExCB, are met.
Monitoring of the quality assurance system of manufacturers carried out by an ExCB.
