Annex D gives a methodology for quantifying the effect of hardware-related common cause failures on the probability of failure.

The standard requires that hazard and risk assessment be carried out for bespoke systems: IEC specifies techniques that should be used for each phase of the life-cycle. The probability metric used in step 3 above depends on whether the functional component will be exposed to high or low demand:. One of these, for the qualitative analysis of hazards, is a framework based on 6 categories of likelihood of occurrence and 4 of consequence.
