62061

ISO/IEC 62061, also known as IEC 62061, is an international standard that specifies the functional safety requirements for safety-related electrical, electronic, and programmable electronic control systems (E/E/PE) used in machinery. The standard provides a structured approach to reduce risk from machine hazards through the safety lifecycle, including hazard analysis, risk assessment, and the design, verification, validation, operation, and maintenance of safety-related control systems.

Scope: It applies to safety-related E/E/PE control systems that perform a safety function such as stopping a

Key concepts: The standard requires a safety lifecycle, a safety requirements specification (SRS), architecture design with

Application and usage: Manufacturers of machinery and automation systems implement IEC 62061 to demonstrate compliance with

Versions: The original IEC 62061 was published in the mid-2000s and was revised with ISO/IEC 62061:2015; this
