The standard requires that hazard and risk assessment be carried out for bespoke systems: The probability metric used in step 3 above depends on whether the functional component will be exposed to high or low demand:. Each has defined their own scheme based upon IEC and other functional safety standards. Certification is third party attestation that a product, process, or system meets all requirements of the certification program.

ifc Annex C gives a worked example of calculateing diagnostic coverage and should be read in conjunction with BS EN The scheme lists the referenced standards and specifies procedures which describes their test methods, surveillance audit policy, public documentation policies, and other specific aspects of their program.

One of these, for the qualitative analysis of hazards, is a framework based on 6 categories of likelihood of occurrence and 4 of consequence. Errors introduced anywhere from the initial concept, risk analysis, specification, design, installation, maintenance and through to disposal could undermine even the most reliable protection.
