SIST EN IEC 61496-2:2021
(Amendment)IEC 61496-2:2020 specifies requirements for the design, construction and testing of electro-sensitive protective equipment (ESPE) designed specifically to detect persons as part of a safety-related system, employing active opto-electronic protective devices (AOPDs) for the sensing function. Special attention is directed to features which ensure that an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given in Annex A of IEC 61496-1:2020 and of this document. This document does not specify the dimensions or configurations of the detection zone and its disposition in relation to hazardous parts for 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. Excluded from this document are AOPDs employing radiation at wavelengths outside the range 400 nm to 1 500 nm. This document can be relevant to applications other than those for the protection of persons, for example, the protection of machinery or products from mechanical damage. In those applications, additional requirements can be necessary, for example, when the materials that are to be recognized by the sensing function have different properties from those of persons. This document does not deal with electromagnetic compatibility (EMC) emission requirements. IEC 61496-2:2020 cancels and replaces the third edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Requirements and test procedures in Part 2 that were found to be common to all ESPEs have been moved to Part 1. Test procedures that are dependent on the sensing technology remain in Part 2.

The reasons and objectives for amending IEC 61496
The main purpose for these amendments to IEC 61496-1 and -2 is as follows:
1) To clarify that Part one of this standard defines only general requirements for non-contact electro sensitive
protective equipment. Part one is intended to be used with a subsequent Part that defines particular
requirements based on the sensing technology used for detection.2) It was discovered that some additional requirements for environmental influences were repeated in parts 2,
3, 4-2 and 4-3. It was decided that these requirements were common to all ESPEs and would be appropriate
to include in Part one.3) Since this standard was written, several new generic standards have been developed that focus on specific
environmental influences that can affect functional safety (e.g. EMC, temperature, vibration). Part one has
been updated to harmonize with the requirements of the new generic standards, including adjusting
terminology and format of tables to match the new standards. It is not intended to change the actual
requirements.4) In the original standard, some of the test procedures for environmental influences were unclear or
incomplete. These procedures have been expanded to provide detailed step by step procedures. Where
appropriate, references to procedures described in the generic test standards are provided.
5) There are Type 3 AOPDs on the market today. The requirements for Type 3 AOPDs are now included in Part
two.6) Some of functional safety fault protection requirements were un-realistic and were generally not possible to
comply with. These requirements have been adjusted slightly.7) Some small corrections and improvements were included throughout the document.
8) It is not intended that these amendments result in significant changes to the requirements. It is believed that
most ESPEs that comply with the existing standards will still be compliant with these reorganized
documents.44-846-CDV.doc

21 4.1.2.1 General requirements22 Replace clause 4.1.2.1 with the following text:
23 The sensing function shall be effective over the detection zone specified by the supplier. No
24 adjustment of the detection zone, detection capability or blanking function shall be possible
25 without the use of a key, key-word or tool.26 The sensing device of a light curtain shall be actuated and the OSSD(s) shall go to and
27 remain in the OFF-state when a test piece in accordance with 4.2.13 is present anywhere
28 within the detection zone either static (at any angle) or moving (with the axis of the cylinder
29 normal to the plane of the detection zone), at any speed between 0 m/s and 1,6 m/s.
30 The sensing device of a light beam device shall be actuated and the OSSD(s) shall go to and
31 remain in the OFF-state when a test piece in accordance with 4.2.13 is present in the beam
32 centre-line, at any point throughout the operating distance, with the axis of the cylinder normal
33 to the axis of the beam.34 Where the supplier states that an AOPD can be used to detect objects moving at speeds
35 greater than those specified above, the above requirements shall be met at any speed up to
36 and including the stated maximum speed(s).37 4.1.2.2.2 Sensing function
38 Replace the second paragraph with the following text:
39 For a type 3 AOPD or a type 4 AOPD, under normal operating conditions, the OSSD(s) shall
40 go to the OFF-state when a reflective object, as specified in 5.2.1.4 is placed as close as
41 practicable in front of the sensing surface of the emitting/receiving elements.
42 4.1.3 Types of ESPE43 Replace entire clause 4.1.3 with the following text:
44 Replacement:
45 In this part of IEC 61496, only type 2, type 3 and type 4 ESPEs are considered. The types
46 differ in their performance in the presence of faults and under influences from environmental
47 conditions. In Part 1, the effects of electrical and electromechanical faults are considered
48 (such faults are listed in Annex B, Part 1).49 NOTE The machine supplier and/or the user will determine which type is required for a particular application.
50 For a type 2 ESPE, in normal operation the output circuit of at least one output signal
51 switching device shall go to the OFF-state when the sensing function is actuated, or when
52 power is removed from the ESPE.44-846-CDV.doc

53 A type 3 ESPE shall fulfil the fault detection requirements of 4.2.2.4.
54 A type 4 ESPE shall fulfil the fault detection requirements of 4.2.2.5.
55 For a type 3 or a type 4 ESPE, in normal operation the output circuit of at least two output
56 signal switching devices shall go to the OFF-state when the sensing function is actuated, or
57 when power is removed from the ESPE.58 When a single safety-related data interface is used to perform the functions of the OSSD(s),
59 then the data interface and associated safety-related communication interface shall meet the
60 requirements of 4.2.4.4 of IEC 61496-1:2012. In this case, a single safety-related data
61 interface can substitute for two OSSDs in a type 3 ESPE or a type 4 ESPE.62 4.2.2.3 Particular requirements for a type 2 ESPE
63 Delete the last paragraph of clause 4.2.2.3.
64 4.2.2.4 Particular requirements for a type 3 ESPE
65 Delete the entire clause 4.2.2.4.
66 4.2.12 Integrity of the AOPD detection capability
67 In Clause 4.2.12, update the references in the second paragraph as follows:
68 If a single fault (as specified in Annex B), which under normal operating conditions (see
69 5.1.2.1 of IEC 61496-1:2012) would not result in a loss of AOPD detection capability but,
70 when occurring with a combination of the conditions specified above, would result in such a
71 loss, that fault together with that combination of conditions shall be considered as a single
72 fault, and the AOPD shall respond to...
