Purpose: To identify the purpose and applicability of this standard and the exclusions from the scope.<\/p>\n
Rationale: The scope excludes requirements for functional safety. Functional safety is addressed in IEC 61508-1. Because the scope includes computers that may control safety systems, functional safety requirements would necessarily include requirements for computer processes and software. The TC108 experts are experts in hardware safety, and have little or no expertise to properly address functional safety requirements.<\/p>\n
