Definition:
A Certification Body (CB) is an independent organization that evaluates and certifies that products, systems, or organizations meet functional safety standards like IEC 61508.
It is the CB that releases the SIL Certificate.
Key Points:
- Certification Bodies must themselves be accredited by Accreditation Bodies.
- Examples include TÜV Rheinland, Exida, and UL.
- Not all CBs are recognized everywhere.
Example:
A safety PLC by Siemens is certified to SC 3 (SIL 3) by Exida. In this case, Exida the Certification body that Siemens worked with. Exida would have done the independent assessment of the PLC.
