What is BS IEC 62671 - Instrumentation and control of nuclear power plant about ?
BS IEC 62671 is an international standard on nuclear power plants instrumentation and control important to safety. The main purpose of BS IEC 62671 is the selection and use of industrial digital devices of limited functionality.
BS IEC 62671 addresses certain devices that contain embedded software or electronically configured digital circuits that have not been produced to other IEC Standards which apply to systems and equipment important to safety in Nuclear Power Plants, but which are candidates for use in nuclear power plants. It provides requirements for the selection and evaluation of such devices where they have dedicated2, limited, and specific functionality, and limited configurability.
BS IEC 62671 provides the acceptance criteria for the selection, evaluation, and use of certain digital devices that have not been developed specifically for use in these nuclear I&C systems. Such devices are very often developed to meet IEC 61508 , and BS IEC 62671 acknowledges that compliance with IEC 61508 can be a key positive factor when qualifying non-nuclear components for nuclear sector use.
Devices addressed by BS IEC 62671 are dedicated devices of limited, specific functionality, that contain or may contain components driven by software or digital circuits designed using software-based...
