CASS Accredited Certification

‚ÄčIn addition to using the CASS methodology for creating evidence of compliance (i.e., for in-house purposes, self-declaration, etc) it has also been used for many years by Certification Bodies to gain an extension to their scope to issue certificates of conformity to IEC 61508 (or related standards).

This approach enables industry to have the added assurance of using the services of a certification body working in accordance with the relevant certification standards (i.e., ISO/IEC  17065, previously ISO/IEC Guide 65) under the auspices of a national accreditation body.

For the Certification Body, the CASS methodology is effectively an “off the shelf” set of technical procedures that can be integrated into their existing procedural framework, saving significant effort and cost.

For the assessee, there are benefits of using a certification service based on the CASS methodology:

  • As the process is open, the assessee can prepare accordingly and avoid any major surprises
  • Any work done previously by the assessee to document evidence of compliance (e.g., for a Self-declaration) can be fed into the certification process

Generally, the main advantages of accredited certification are:

  • Increased level of rigour and assurance
  • Can ensure a high level of independence (e.g.,  where higher SILs are involved)
  • Certificates can help support marketing of the product or service
  • Demonstrates due diligence from an plant owner/operator

Important Note: Certification bodies that use the CASS method and have received national accreditation (to ISO/IEC 17065) for the relevant functional safety standard may use the CASS Mark (available on request via Contacting CASS).
