IECEx Equipment Scheme

What is the benefits of an IECEx 02 scheme Certification?

Manufacturers can use an IECEx certificate to obtain national certification in the member countries participating in the IECEx Scheme.

In other words, IECEx’s certification of Ex products represents an approval process that is globally recognized, thereby supporting international trade. International acceptance means that it takes manufacturers less time to get products to market and manufacturers testing, and certification costs are reduced. The IECEx system also allows for countries to address their unique, local safety concerns, which are recognized as National Differences.

IECEx has created an international database of approved Ex products. Products granted an IECEx certificate by KSC will be added to the database.

What is involved in testing and assessment by KSC for IECEx Certification?

KSC undertakes testing of samples of an Ex equipment under the hazardous conditions in which it will be installed and used. Such testing is used to prove that the equipment complies with all the requirements of the relevant general and specific IEC Standards, as well as to any National Differences required. Of particular importance is the testing undertaken to ensure that protection techniques included in the product’s design are effective, ensuring that the product is safe, even when installed and used in a hazardous environment. The result of assessment and tests carried out and is an IECEx Test Report (ExTR).

KSC also conducts audits of the manufacturer of the Ex equipment. KSC undertakes an inspection of all the locations where the product will be made to ensure that each location is capable of manufacturing products identical in design and performance to the tested sample. The result of this quality assessment is a Quality Assessment Report (QAR).

Based on the successful results of both ExTR and QAR assessments, KSC issues an IECEx Certificate of Conformity (CoC) which becomes publicly available on the online on the IECEx website.

How is an IECEx Certification for an Ex product indicated?

Once an IECEx certificate has been issued, KSC then assigns a unique IECEx Certificate of Conformity number to be placed on the product nameplate and literature to demonstrate compliance. When a manufacturer uses the services of KSC, the final marking on an IECEx-certified product illustrates that the product has successfully completed the IECEx certification process.


KSC welcomes manufacturers who wish to achieve an IECEx certification for Ex equipment.
