Scope

This standard machinery safety-related electrical and electronic and programmable electronic control systems (SRECS) design, integration and validation requirements
And give advice (see Notes 1 and 2).
This standard applies to individual or combined way to use a control system to enable non-portable working machine to perform safety-related
Control functions, including a group of machines working together in a coordinated manner, does not apply to portable working machine.
Note 1.In this standard, the "electrical control system," the term means "electrical, electronic and programmable electronic (E/E/PE) control system", "SRECS" represents
"Safety related electrical, electronic and programmable electronic control systems."
Note 2.In this standard, the design assumptions complex programmable electronic subsystems or subsystem elements related to IEC 61508 requirements. This standard provides consumers
Law, not of such elements as SRECS subsystem and subsystem components development.
This standard is applicable standards do not restrict or impede technological progress. It does not include the desired or required by other standards or regulations for the protection of personal
From danger all the requirements (for example protection, non-electrical or non-electrical interlock control). Each type of machine has unique requirements to meet the needs,
To provide adequate security.
This standard.
--- Relates only expected to reduce the risk of personal injury or health hazards of direct access to the machine or use the machine directly caused by safety features
Wide requirements;
--- Limited risk of the machine itself or dangerous machine groups to work together in a coordinated manner arising directly;
Note 3.reduce the risk caused by other hazards require related fields in the standard. For example, the machine is part of the processing activities, the mechanical and electrical
Control system functional safety requirements should meet other requirements (such as GB/T 21109), as long as the safety-related processing.
--- Does not provide non-electrical machinery (for example, hydraulic, pneumatic) control elements of the performance requirements;
Note 4.Although this standard specifically for electrical control system, but the provisions of the framework and methodology can be applied to other art control system security
Related components.
Electrical Hazard --- does not include electrical control equipment itself caused (eg electric shock, see GB 5226.1).
The objective of this standard specific provisions in Table 2.
