Description:Gives the aspects to be considered when electrical/electronic/programmable electronic systems (E/E/PESs) are used to carry outsafety functions. A major objective is to facilitate thedevelopment of application sector international standards by thetechnical committees responsible for the application sector. This allows the relevant factors associated with the application, to be fully taken into account and thus meet the need of theapplication sector. Applicable to safety-related systems when one or more of such systems incorporates electrical/electronic/programmable electronic devices.

1 Overall safety lifecycle: overview
2 Safety integrity levels: target failure measures for a
safety function, allocated to an E/E/PE safety-related
system operating in low demand mode of operation
3 Safety integrity levels: target failure measures for a
safety function, allocated to an E/E/PE safety-related
system operating in high demand or continuous mode of
operation

functional safety assessment (overall safety lifecycle
phases 1 to 8 and 12 to 16 inclusive (see figure 2))
5 Minimum levels of independence of those carrying out
functional safety assessment (overall safety lifecycle
phase 9 - includes all phases of E/E/PES and software
safety lifecycles (see figures 2, 3 and 4))
