Safety of machinery -- Safety-related parts of control systems -- Part 1: General principles for design
This part of ISO 13849 provides safety requirements and guidance on the principles for the design of safety-related parts of control systems. For these parts, it specifies categories and describes the characteristics of their safety functions, including programmable systems for all machinery and for related protective devices.
This part of ISO 13849 applies to all safety-related parts of control systems, regardless of the type of energy used, e.g. electrical, hydraulic, pneumatic, mechanical. It does not specify which safety functions and which categories shall be used in a particular case.
This part of ISO 13849 applies to all machinery applications for professional and non-professional use. Where appropriate, it can also be applied to the safety-related parts of control systems used in other technical applications.
