This International Standard specifies requirements and makes recommendations for the design, integration and validation of safety-related control systems (SCS) for machines. It is applicable to control systems used, either singly or in combination, to carry out safety functions on machines that are not portable by hand while working, including a group of machines working together in a co-ordinated manner.
This standard is machinery sector specific standard within the framework of the IEC 61508 series.
The design of complex programmable electronic subsystems or subsystem elements is not in the scope of this standard. This is in the scope of IEC 61508 or standards linked to it, see Figure 1.
The main body of this sector standard specifies general requirements for the design, and verification of a safety-related control system intended to be used in high/continuous demand mode.
Specific requirements for design, and verification of a safety-related control system intended to be used in low demand mode are given in normative Annex D.
NOTE 1 – It’s recognized that a subsystem can be shared by high and low demand functions.
