Accredited Certification for Safety Systems…..

…. to IEC 61508 and related standards

CASS (Conformity Assessment for Safety-Related Systems) Guide CASS is a scheme for assessing the compliance of safety related systems with the requirements of IEC 61508 and associated standards. It provides a systematic approach to be used by certification bodies and others when assessing compliance at all stages from the specification of safety requirements through the design, development and manufacture of system components to integration, commissioning, operation and maintenance. At each stage CASS takes the conformity assessor through the logical steps of defining the scope of the assessment, the target of evaluation, the requirements to be met and the process of demonstrating and recording conformity.

How does your certificate measure up?

CASS is run by The CASS Scheme Ltd, a not-for-profit company whose members are drawn from a wide range of organizations which use IEC 61508. The company develops and publishes the documentation

necessary for carrying out the assessments as well as providing the criteria and procedure for assessing the competence of assessors. The company also licenses the use of the CASS logo by certification bodies which meet the CASS scheme requirements.

Accreditation of certification bodies to the criteria specified in the CASS scheme is intended to ensure that the certification bodies operate with:

Integrity – independence, impartiality, competence, objectivity

Transparency of the certification requirements and process

Consistency of results between different certification bodies ensuring credibility to suppliers, users and regulators.

Guide to FSCAFor the highest level of assurance, CASS provides the technical criteria for the accreditation of certification bodies by national bodies such as the United Kingdom Accreditation Service (UKAS). In addition to verifying the technical competence of the certification bodies, the accreditation process establishes their independence and integrity for the conduct of effective conformity assessment.
