exida, a provider of certifications for automation equipment uses in safety instrumented systems, has discovered counterfeit certificates claiming exida certification to Safety Integrity Level (SIL) 3 capability of IEC 61508.

The company advises safety practitioners to consult the Safety Automation Equipment List (SAEL) at www.sael-online.com to verify certification validity. The SAEL is a directory of safety-certified equipment assessed by certification bodies, such as exida, TÜV Rh., TÜV Süd, and TÜV Nord.

Authentic certification helps process manufacturers design and implement safety instrumented systems that comply with the IEC 61511/ISA 84 functional safety standard (as required by law in some areas of the world).

In addition, authentic certification indicates that the product hardware and software design, the safety manual, as well as the processes used for development, testing, and quality control, comply with the requirements of the IEC 61508 international standard.
