This document specifies general requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (3.5) (ESPE) designed specifically to detect persons or part of a person as part of a safety-related system. Special attention is directed to functional and design requirements that ensure an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given in Annex A.
NOTE 1 "Non-contact" means that physical contact is not required for sensing.
This document is intended to be used with a subsequent part of IEC 61496 [1] that provides particular requirements based on the sensing technology.
EXAMPLE This document and part-2 are used for AOPDs; this document and part-3 are used for AOPDDRs.
NOTE 2 The applicability and relationship of this product specific standard with standards on functional safety of safety-related control systems and generic product standards is described in Annex C
This document does not specify the dimensions or configuration of the detection zone and its disposition in relation to hazards in any particular application, nor what constitutes a hazardous state of any machine. It is restricted to the functioning of the ESPE and how it interfaces with the machine.
While a data interface can be used to control optional safety related ESPE functions (Annex A), this document does not provide specific requirements. Requirements for these safety-related functions can be determined by consulting other standards (for example, IEC 61508 (all parts) [3], IEC 62046 [4] and ISO 13849-1 [5]).
This document can be relevant to applications other than those for the protection of persons, for example for the protection of machinery or products from mechanical damage. In those applications, different requirements can be appropriate, for example when the materials that have to be recognized by the sensing function have different properties from those of persons.
This document does not deal with requirements for ESPE functions not related to the protection of persons (e.g. using sensing unit data for navigation).
This document does not deal with electromagnetic compatibility (EMC) emission requirements.
This document does not provide specific measures for security aspects (e.g. physical, IT-security, cyber security).
