IEC 61496-3:2025(Main)

Safety of machinery - Electro-sensitive protective equipment - Part 3: Particular requirements for active opto-electronic protective devices responsive to diffuse reflection (AOPDDR)

IEC 61496-3:2025 specifies additional requirements for the design, construction and testing of non‑contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons or parts of persons as part of a safety-related system, employing active opto-electronic protective devices responsive to diffuse reflection (AOPDDRs) for the sensing function. Special attention is directed to requirements which ensure that an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given both in Annex A of this document and in Annex A of IEC 61496‑1:2020.
NOTE "Non-contact" means that physical contact is not required for sensing.
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.
AOPDDRs are devices that have either
- one or more detection zone(s) specified in two dimensions (AOPDDR-2D), or
- one or more detection zone(s) specified in three dimensions (AOPDDR-3D)
wherein radiation in the near infrared range is emitted by an emitting element(s). When the emitted radiation impinges on an object (for example, a person or part of a person), a portion of the emitted radiation is reflected to a receiving element(s) by diffuse reflection. This reflection is used to determine the position of the object.
Opto-electronic devices that perform only a single one-dimensional spot-like distance measurement, for example, optical proximity switches, are not covered by this document.
This document is limited to ESPE that do not require human intervention for detection. It is limited to ESPE that detect objects entering into or being present in a detection zone(s).
This document does not address those aspects required for complex classification or differentiation of the object detected.
This document does not address requirements and tests for outdoor application.
Excluded from this document are AOPDDRs employing radiation with the peak of wavelength outside the range 820 nm to 1 100 nm, and those employing radiation other than that generated by the AOPDDR itself. For sensing devices that employ radiation of wavelengths outside this range, this document can be used as a guide. This document is relevant for AOPDDRs having a minimum detectable object size in the range from 30 mm to 200 mm.
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 are recognized by the sensing function have different properties from those of persons and their clothing.
This document does not deal with electromagnetic compatibility (EMC) emission requirements.
This fourth edition cancels and replaces the third edition published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) some requirement clauses and test procedures have been adapted or removed because they have been consolidated in IEC 61496-1:2020 (e.g. 5.4.6.2 Light sources and Clause A.9);
b) change of the minimum probability of detection and fault detection requirements for Type 2 AOPDDR;
c) using the AOPDDR as a trip device is described as an optional function in Clause A.13.

IEC TS 61496-5:2023(Main)

Safety of machinery – Electro-sensitive protective equipment - Part 5: Particular requirements for radar-based protective devices

IEC TS 61496-5:2023 provides particular requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to provide whole-body detection of a person or persons as part of a safety-related system, employing radar protective devices (RPDs) responsive to diffuse reflection of radar signals for the sensing function using frequency-modulated continuous-wave (FMCW) technique. 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 Annex A of this document.
The requirements given in this document are related to the detection of adult persons being present in an industrial manufacturing environment.
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.
This document does not consider the aspects of a moving RPD application. Additional consideration can be necessary, if the RPD supplier specifies the RPD for use on moving application.
Additional requirements and tests can apply if setup of the RPD differs from Figure 2 and Figure 4.
Where this document does not contain all necessary provisions, IEC TS 62998-1 is used.
For those aspects not considered in this document it is also possible to additionally use provisions from IEC TS 62998-1.
Excluded from this document are RPDs that employ electromagnetic radiation outside the range 9 GHz to 81 GHz (identified as subset of band 10 and band 11 in accordance with ITU Radio Regulations). For sensing devices that employ electromagnetic radiation outside this range, this document can be used as a guide. National regulations can limit the available frequencies.
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 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).
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, IEC 62046, IEC 62061, and ISO 13849-1).
This document does not deal with EMC emission requirements.

IEC TS 63394:2023(Main)

Safety of machinery - Guidelines on functional safety of safety-related control systems

IEC TS 63394:2023 In the context of the safety of machinery, the sector standard IEC 62061, along with ISO 13849 1, provides requirements to manufacturers of machines for the design, development and integration of safety-related control systems (SCS) or safety-related parts of control systems (SRP/CS), depending on technology used (mechanical, pneumatic, hydraulic or electrical technologies) to perform safety function(s). This document does not replace ISO 13849-1 and IEC 62061. This document gives additional guidance to the application of IEC 62061 or ISO 13849-1.
This document:
– gives guidelines and specifies additional requirements for specific safety functions based on the methodology of ISO 12100, which are relevant in machinery and respecting typical boundary conditions of machinery;
– considers safety functions which are designed for high demand mode of operation yet are rarely operated, called rarely activated safety functions;
– gives additional information for the calculation of failure rates using other (non-electronic) technologies based e.g. on Weibull distribution, because all the formula defined in IEC 62061 and ISO 13849-1 are based on exponential distribution.
Therefore, the basis for these guidelines and additional requirements is
– a typical classification of safety functions;
– a consideration of typical architectures used for designing safety functions;
– a consideration of modes of operation of safety functions;
– the derivation and evaluation of PFH formulas for subsystems considering the used technology.
This document does not address low demand mode of operation according to IEC 61508.
This document does not take into account either layer of protection analysis (LOPA) or basic process control system (BPCS), according to IEC 61511 as a risk reduction measure.
This document considers all lifecycle phases of the machine regarding functional safety, and SCS or SRP/CS.

IEC TS 63074:2023(Main)

Safety of machinery - Security aspects related to functional safety of safety-related control systems

IEC TS 63074:2023 identifies the relevant aspects of the IEC 62443 series related to security threats and vulnerabilities that are considered for the design and implementation of safety-related control systems (SCS) which can lead to the loss of the ability to maintain safe operation of a machine.
Typical security aspects related to the machine with potential relation to SCS are:
– vulnerabilities of the SCS either directly or indirectly through the other parts of the machine which can be exploited by security threats that can result in security attacks (security breach);
– influence on the safety characteristics and ability of the SCS to properly perform its function(s);
– typical use case definition and application of a corresponding threat model.
Non-safety-related aspects of security threats and vulnerabilities are not considered in this document.
The focus of this document is on intentional malicious actions. However, intentional hardware manipulation (e.g. wiring, exchange of components) or foreseeable misuse by physical manipulation of SCS (e.g. physical bypass) is not considered in this document.
This document does not cover security requirements for information technology (IT) products and for the design of devices used in the SCS (e.g., product specific standards can be available, such as IEC TS 63208).

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. The detection principle is based on the evaluation of images from different viewing points (stereoscopic view) for the determination of distance information. This distance information is used to determine the position of an object(s).
– This document is limited to vision based ESPEs with fixed distances (stereo base) and fixed directions of the optical axes using a fixed focal length.
– It is limited to vision based ESPEs that do not require human intervention for detection.
– It is limited to vision based ESPEs that detect objects entering into or being present in a detection zone(s).
– It is limited to VBPDSTs employing radiation at wavelengths within the range 400 nm to 1 500 nm.
– This document does not address those aspects required for complex classification or differentiation of the object detected.
– This document does not consider the aspects of a moving ESPE installation.
Additional requirements and tests can apply in the following cases:
– Use of multi-spectral (colour) techniques;
– Setups other than as shown in Figure 2 and Figure 3 (e.g. changing backgrounds, horizontal orientation of the optical axis with respect to the floor);
– Intended for outdoor applications.
This document is relevant for VBPDSTs having a stated detection capability up to 200 mm. This document can be relevant to applications other than those for the protection of persons or parts of persons like arm or fingers (in the range 14 mm to 200 mm), 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 EMC emission requirements.
IEC TS 61496-4-3:2022 cancels and replaces the first edition published in 2015-05. This edition constitutes a technical revision. This edition includes the following technical changes with respect to the previous edition:
a) Some requirement clauses and test procedures have been adapted or removed because they have been consolidated in IEC 61496-1:2020 (e.g. 5.4.6.2 Light sources or Clause A.9).
