This document set out the requirements for the development and integration of safety-related sensors (3.3.14) (SRS ) and safety-related sensor systems (3.3.15) (SRSS ) used for the protection of persons with particular attention to systematic capability (3.1.4).
This generic product standard applies if protection of persons is to be performed by using sensors.
NOTE 1 The appliance and relationship of this generic product standard with standards on functional safety of safety-related control systems and product specific standards is described in Annex A.
This generic product standard can be applied also for other protective goals like protection of the environment or prevent production goods damages.
The examination of detection capability (3.1.6) as part of the systematic capability (3.1.4) using different product standards is described in Annex A.
The requirements and methods set out in this document are intended for the purpose of protection of persons by:
– detection (3.1.5) of potentially hazardous objects;
– detection (3.1.5) of a body, parts of a body and objects associated to parts of a body entering a hazardous area; or
– classification and/or discrimination of these against other objects.
NOTE 2 The application of SRS/SRSS in a public setting can require the detection (3.1.5) of not only persons, but also their associated equipment, such as wheelchairs, walking sticks or infusion stands.
Performance classes of SRS/SRSS are defined in accordance with existing standards on functional safety of safety-related control systems (e.g. IEC 62061, IEC 61508 (all parts), and ISO 13849 (all parts)).
NOTE 3 By correlating to existing PL or SIL, we have achieved simplification for end users.
Specific attention is devoted to the evaluation of the detection capability (3.1.6) and dependability (3.2.2) of the detection capability (3.1.6) . Environmental conditions and limits for indoor and outdoor use are defined that influence the sensing function and the dependability (3.2.2) of the detection capability (3.1.6).
NOTE 4 Environmental influences, their classification and test (3.7.10) procedures are primarily specified in accordance with generic environmental standards. In the absence of respective standards, more specific requirements and tests are described.
This document can be relevant for applications other than the protection of persons in industry (3.3.17), such as agriculture or public transportation (e.g. metro stations).
This document does not consider or address proven in-use (e.g. processes or elements) as defined in IEC 61508-2 [2].
