This part of GB/T 16855 specifies the safety requirements and guiding principles for the design and integration of control system safety related components (SRP/CS), including software design. This section specifies the characteristics of these SRP/CS components, including the performance levels required to perform safety functions. This section applies to SRP/CS with high requirements and continuous modes for all types of machinery, regardless of the technology and energy used (electrical, hydraulic, pneumatic, mechanical, etc.). This section does not specify safety functions or performance levels for special applications. This section provides specific requirements for SRP/CS using programmable electronic systems. This section does not provide specific design requirements for SRP/CS products, but principles such as the given categories or performance levels can be adopted. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document.
