This document specifies a methodology and provides related requirements, recommendations and guidance for the design and integration of safety‐related parts of control systems (SRP/CS) that perform safety functions, including the design of software.
This document applies to SRP/CS for high demand and continuous modes of operation including their subsystems, regardless of the type of technology and energy (e.g. electrical, hydraulic, pneumatic, and mechanical). This document does not apply to low demand mode of operation.
