There are very few nationally accredited bodies that can issue nationally accredited certifications, including FM, TUV, and Sira. Many unaccredited consulting FIRMS issue certificates that indicate they have reviewed the product and / or process for conformance to certain PARTS of the IEC 61508 standard. The standard does not mandate that certain companies or agencies are able to certify products and systems. Rather, it is suggested that analysis is either conducted or validated by an INDEPENDENT third party.
