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 or IEC 61511.
Key Points:
- Certification Bodies must themselves be accredited by Accreditation Bodies.
- Examples include TÜV Rheinland, Exida, and UL.
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.
