Safety of machinery - Electro-sensitive protective equipment - Part 1: General requirements and tests (IEC 61496-1:2020)
IEC 61486-1:2020 specifies general requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (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.
This document is intended to be used with a subsequent part of IEC 61496 that provides particular requirements based on the sensing technology.
Where a part covering the sensing technology does not exist, IEC TS 62998-1 is used.
Where the IEC 61496 series does not contain all necessary provisions, IEC TS 62998-1 is used.
It is an additional possibility to combine those aspects covered by the IEC 61496 series in addition to IEC TS 62998-1.
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), IEC TS 62046, IEC 62061, and ISO 13849-1).
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.
IEC 61486-1:2020 cancels and replaces the third edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) It has been clarified that some requirements for ESPEs that are dependent on sensing technology are not included in IEC 61496-1. They are provided in a subsequent part of IEC 61496.
b) Requirements for protection against environmental influences from subsequent parts of IEC 61496 that are common to all ESPEs have been consolidated into IEC 61496-1.
c) Some test procedures in IEC 61496-1 were incomplete. They have been expanded with more detail and step by step procedures.
d) Some requirements and procedures in IEC 61496-1 are now covered by new generic machine safety standards. The requirements in IEC 61496-1 have been harmonized with references to the new generic standards.

Sécurité des machines - Equipements de protection électro-sensibles - Partie 1: Exigences générales et essais (IEC 61496-1:2020)
L'IEC 61496-1:2020 définit les exigences générales de conception, de construction et d'essai des équipements de protection électrosensibles (ESPE) sans contact spécifiquement conçus pour détecter des personnes au sein d’un système relatif à la sécurité. Une attention particulière est accordée aux exigences de fonctionnement et de conception assurant la satisfaction aux performances relatives à la sécurité appropriées. Un ESPE peut proposer des fonctions facultatives liées à la sécurité: les exigences relatives à celles-ci sont données à l’Annexe A.
L'IEC 61496-1:2020 est destiné à être utilisé avec une partie ultérieure de l’IEC 61496 qui définit des exigences particulières en fonction de la technologie de détection.
En l’absence d’une partie couvrant la technologie de détection, l’IEC TS 62998-1 est utilisée.
Dans le cas où la série IEC 61496 ne contient pas toutes les dispositions nécessaires, l’IEC TS 62998-1 est utilisée.
Il est en outre possible de combiner ces aspects couverts par la série IEC 61496 à l’IEC TS 62998-1.
Le présent document ne spécifie ni les dimensions ou la configuration de la zone de détection, ni sa disposition par rapport aux dangers dans toute application particulière, ni ce qui constitue un état dangereux pour toute machine donnée. Il se limite au fonctionnement de l’ESPE et à son interface avec la machine.
Bien qu’une interface de données puisse être utilisée pour commander des fonctions de l'ESPE relatives à la sécurité facultatives (Annexe A), le présent document ne fournit pas d’exigences particulières. Les exigences liées à ces fonctions relatives à la sécurité peuvent être déterminées en consultant d'autres normes (par exemple, l'IEC 61508 (toutes les parties), l’IEC 62046, l’IEC 62061, et l'ISO 13849-1).
Le présent document peut être pertinent pour des applications autres que la protection des personnes, par exemple la protection des machines ou des produits contre des dommages mécaniques. Dans ces applications, des exigences différentes peuvent être nécessaires, par exemple lorsque les matériaux qui doivent être reconnus par le dispositif de détection ont des caractéristiques différentes de celles des personnes.
Le présent document ne traite pas des exigences relatives aux fonctions de l’ESPE non liées à la protection des personnes (en utilisant, par exemple, les données de l’élément de détection en matière de navigation).
Le présent document ne traite pas des exigences d’émission relatives à la compatibilité électromagnétique (CEM).
L'IEC 61496-1:2020 annule et remplace la troisième édition parue en 2012. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) Il a été défini que certaines exigences relatives aux ESPE dépendant de la technologie de détection n’étaient pas incluses dans l’IEC 61496-1. Ces exigences sont fournies dans une partie ultérieure de l’IEC 61496.
b) Les exigences de protection contre les influences environnementales issues des parties ultérieures de l’IEC 61496 et qui sont communes à tous les ESPE ont été consolidées dans l’IEC 61496-1.
c) Certaines procédures d’essai de l’IEC 61496-1 étaient incomplètes. Elles ont été enrichies par des procédures plus détaillées et étape par étape.
d) Certaines exigences et procédures de l’IEC 61496-1 sont désormais couvertes par de nouvelles normes génériques relatives à la sécurité des machines. Les exigences de l’IEC 61496-1 ont été harmonisées avec des références à ces nouvelles norme

Overview
EN IEC 61496-1:2020 - "Safety of machinery - Electro‑sensitive protective equipment - Part 1: General requirements and tests" defines general design, construction and test requirements for non‑contact electro‑sensitive protective equipment (ESPE) used as part of safety‑related systems. This Part 1 sets functional, design and environmental expectations that ensure ESPE achieve appropriate safety‑related performance. It is a general (technology‑neutral) foundation intended to be used with subsequent IEC 61496 parts that cover specific sensing technologies; where no specific part exists, IEC TS 62998‑1 is used.
Key topics and requirements
- Scope and limits: Focuses on ESPE functioning and machine interface; it does not define detection‑zone geometry, machine hazard states or EMC emission requirements.
- Functional requirements: Sensing function, normal operation, response time and types/required safety performance (Types 1–4 referenced).
- Design requirements: Electrical supply, fault detection, output signal switching devices (OSSDs), indicators, adjustments, separation/disconnection, non‑electrical components, and measures against common‑cause failures.
- Environmental requirements: Ambient temperature, humidity, electrical disturbances, mechanical stresses, enclosures and light interference - consolidated from subsequent IEC 61496 parts where common to all ESPEs.
- Testing: Type tests, functional tests (sensing, response time, periodic tests), performance testing under fault conditions, environmental tests, and validation of programmable or complex integrated circuits with software considerations.
- Optional functions: Annex A covers optional safety‑related functions (e.g., External Device Monitoring (EDM)); specific data‑interface controls are acknowledged but are to be addressed by other functional safety standards as needed.
- Marking & documentation: Requirements for identification, safe use instructions and accompanying documents for installation, maintenance and validation.
Practical applications
EN IEC 61496‑1:2020 applies to equipment such as:
- Safety light curtains, safety scanners, area sensors and optoelectronic ESPEs

INTRODUCTION
An electro-sensitive protective equipment (ESPE) is applied to machinery presenting a risk of
personal injury. It provides protection by causing the machine to revert to a safe condition
before a person can be placed in a hazardous situation.
This document provides general design and performance requirements of ESPEs for use over
a broad range of applications. Essential features of equipment meeting the requirements of
this document are the appropriate level of safety-related performance provided and the
built-in periodic functional checks/self-checks that are specified to ensure that this level of
performance is maintained.
Each type of machine presents its own particular hazards and it is not the purpose of this
document to recommend the manner of application of the ESPE to any particular machine.
The application of the ESPE is a matter for agreement between the equipment supplier, the
machine user and the enforcing authority, and in this context attention is drawn to the relevant
guidance established internationally, for example ISO 12100.
This document specifies technical requirements of electro-sensitive protective equipment. The
application of this document may require the use of substances and/or test procedures that
could be injurious to health unless adequate precautions are taken. Conformance with this
document in no way absolves either the supplier or the user from statutory obligations relating
to the safety and health of persons during the use of the equipment covered by this document.
The requirements of this document are highly dependent on analysis and expertise in specific
test and measurement techniques. In order to provide a high level of confidence, independent
review is recommended.

SAFETY OF MACHINERY –
ELECTRO-SENSITIVE PROTECTIVE EQUIPMENT –
Part 1: General requirements and tests
1 Scope
This part of IEC 61496 specifies general requirements for the design, construction and testing
of non-contact electro-sensitive protective equipment (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 "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 that provides
particular requirements based on the sensing technology.
EXAMPLE This document and IEC 61496-2 are used for AOPDs; this document and IEC 61496-3 are used for
AOPDDRs.
Where a part covering the sensing technology does not exist, IEC TS 62998-1 is used.
Where the IEC 61496 series does not contain all necessary provisions, IEC TS 62998-1 is
used.
It is an additional possibility to combine those aspects covered by the IEC 61496 series in
addition to IEC TS 62998-1.
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), IEC 62046, IEC 62061, and ISO 13849-1).
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.

The article discusses the SIST EN IEC 61496-1:2020 standard, which addresses the safety of machinery and electro-sensitive protective equipment (ESPE). The standard outlines general requirements and tests for non-contact ESPE that are designed to detect people or body parts as part of a safety system. The document emphasizes the importance of functional and design requirements to ensure proper safety performance. Optional safety-related functions of ESPE are also mentioned in Annex A. The article clarifies that "non-contact" means physical contact is not necessary for sensing. The standard is intended to be used alongside another part of IEC 61496 that provides specific requirements based on sensing technology. The article provides examples of how this document is used in conjunction with other parts for different applications. If a part covering the sensing technology does not exist, IEC TS 62998-1 is used as an alternative. The document does not specify the dimensions or configuration of the detection zone, its placement in relation to hazards, or what qualifies as a hazardous state for machines. It focuses solely on the functioning of the ESPE and its interface with the machine. Although a data interface may be used for controlling optional safety-related ESPE functions, specific requirements for these functions are not provided in this document. Other standards such as IEC 61508, IEC 62046, IEC 62061, and ISO 13849-1 can be consulted for determining requirements for these safety-related functions. While the primary application of this standard is for the protection of persons, it can also be relevant for the protection of machinery or products from mechanical damage. Different requirements may apply in these cases, especially when the properties of the materials to be detected by the sensing function differ from those of people. The document does not address requirements for ESPE functions unrelated to the protection of persons, such as using sensing unit data for navigation. Electromagnetic compatibility (EMC) emission requirements are also not covered in this document.

記事タイトル：SIST EN IEC 61496-1:2020 - 機械の安全 - 電気感応性保護装置 - 第1部：一般要件と試験（IEC 61496-1:2020） 記事内容：このIEC 61496の一部では、非接触電気感応性保護装置（ESPE）の設計、構造、試験の一般要件について特定の指令を定めています。これは、安全関連システムの一環として特に人を検出するために設計されたESPEに関して機能的および設計要件に注目しています。ESPEにはオプションの安全関連機能を含めることができますが、その要件は付録Aで規定されています。 「非接触」とは、検出に物理的な接触が必要ないことを意味します。 この文書は、センシング技術に基づく具体的な要件を提供するIEC 61496シリーズの後続部分と共に使用することを意図しています。例えば、この文書とIEC 61496-2はAOPDに使用され、この文書とIEC 61496-3はAOPDDRsに使用されます。センシング技術をカバーする部分が存在しない場合、IEC TS 62998-1が使用されます。IEC 61496シリーズに必要なすべての規定が含まれていない場合、IEC TS 62998-1を追加して組み合わせることができます。 この文書は、特定の応用における検出ゾーンの寸法や配置、および機械の危険状態の定義については規定していません。これはESPEの機能と機械とのインターフェースに制約されています。オプションの安全関連ESPE機能を制御するためにデータインターフェースを使用することはできますが、この文書では具体的な要件を提供していません。これらの安全関連機能の要件は、他の規格（例：IEC 61508（すべての部分）、IEC 62046、IEC 62061、ISO 13849-1）を参照して決定することができます。 この文書は、人の保護以外にも機械や製品の保護など、他の応用にも関連する場合があります。ただし、これらの応用には異なる要件が適切な場合があります。例えば、検出機能が人とは異なる特性を持つ材料を認識する必要がある場合などです。この文書は、人の保護以外のESPEの機能に関連する要件には触れていません。また、電磁的適合性（EMC）の放射要件には触れていません。
この記事は、SIST EN IEC 61496-1:2020という規格について説明しています。この規格は、機械の安全性と非接触型の電気感知保護装置（ESPE）に関する一般的な要求事項およびテストを定めています。ESPEは特に安全関連システムの一部として、人や人の一部を検知するために設計されています。適切な安全性能が確保されるための機能とデザインの要件に特に注意が払われています。ESPEには選択的な安全関連機能が含まれる場合があり、それに関する要件は付録Aに記載されています。 「非接触型」とは、検知に物理的な接触が必要ないことを意味します。 この規格は、感知技術に基づいた具体的な要件を提供するIEC 61496の別のパートと併用することを意図しています。具体的な感知技術にかかるパートが存在しない場合は、IEC TS 62998-1が利用されます。 IEC 61496シリーズに必要な規定がすべて含まれていない場合、IEC TS 62998-1が利用されます。 IEC 61496シリーズとIEC TS 62998-1を組み合わせて使用することも可能です。 この規格では、特定の応用における検知領域の寸法や配置、および危険要素との関係、および機械の危険な状態の定義は明記されていません。この規格は、ESPEの機能とそれが機械とどのように連携するかに制約されています。 データインターフェースを使用して選択的な安全関連ESPE機能を制御する場合、この規格では具体的な要件を提供しません。これらの安全関連機能の要件は、他の規格（例：IEC 61508（すべてのパート）、IEC 62046、IEC 62061、ISO 13849-1）を参照して決定することができます。 この規格は、人の保護以外の目的（例：機械や製品の機械的な損傷からの保護など）にも関連する場合があります。これらの場合、特に感知機能が検知する材料の特性が人と異なる場合、異なる要件が適用される場合があります。 この規格は、人の保護と関連しないESPE機能の要件には触れていません（例：センシングユニットデータを使用したナビゲーションなど）。 また、この規格は電磁的互換性（EMC）の放射要件についても触れていません。
The article discusses the SIST EN IEC 61496-1:2020 standard, which focuses on the safety of non-contact electro-sensitive protective equipment (ESPE). The standard specifies general requirements for the design, construction, and testing of ESPE that is used to detect persons or body parts as part of a safety-related system. It emphasizes the functional and design requirements necessary to ensure appropriate safety performance. The document is intended to be used in conjunction with another part of the standard that provides specific requirements based on the sensing technology. If a part covering the sensing technology does not exist, IEC TS 62998-1 is used instead. The article also clarifies that the standard does not specify the dimensions or configuration of the detection zone or what constitutes a hazardous state for a machine. Additionally, the article states that while a data interface can be used to control optional safety-related ESPE functions, the standard does not provide specific requirements for these functions, and other standards should be consulted. The standard can be applicable to applications other than the protection of persons, such as the protection of machinery or products. However, different requirements may be appropriate for these applications. Finally, the article notes that the standard does not address electromagnetic compatibility emission requirements.
