The CASS Scheme

Sira has gained accreditation from the United Kingdom Accreditation Service (UKAS) to carry out its certification activities in accordance with The CASS Scheme (Conformity Assessment of Safety-related Systems).

The Scheme ensures transparency in the certification process and minimises costs for clients, and offers assistance in preparing the necessary technical files. Accreditation by UKAS provides both our customers and their clients with the internationally recognised assurance of the competence of Sira’s personnel and certification processes.

CASS is a certification scheme set up and managed by all those sectors of industry with an interest in accredited certification to IEC 61508.

The CASS Scheme provides a rigourous and internationally acceptable structure under which certification of safety related systems can take place. It ensures consistency in the assessment of both products and functional safety management systems and clarifies issues of interpretation with the generic standard.

The scheme is operated through independent third-party certification bodies (such as ourselves) that are accredited to the European and International accreditation standards for the certification of products and processes.
