Safety Related Sensors (IEC 62998)
Scope
safety related sensors and sensor systems used for protection of persons with special attention to systematics
- protection of persons is to be performed by using sensors, and
- standards for functional safety of electrical control systems address sensor(s) as subsystem or subsystem element, and
- product specific sensor standards (e.g. IEC 61496 , IEC 60947-5-2) do not contain all necessary provisions, or product specific sensor standards are not developed.
FUSION
3.15.3 - fusion the act or process of combining or associating data or information regarding one or more entities considered in an explicit or implicit knowledge framework to improve one’s capability (or provide a new capability) for detection, identification, or characterization of that entity
3.15.1 - alignment
- processing of SRS measurements to achieve a common time base and a common spatial reference 3.15.2 - diversity different means of performing a required function Note to entry: Diversity may be achieved by different physical methods or different design approaches. [SOURCE: IEC 61508-4:2010, 3.3.7]
