Safety of machinery - Electro-sensitive protective equipment - Part 1: General requirements and tests
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.
Sicherheit von Maschinen - Berührungslos wirkende Schutzeinrichtungen - Teil 1: Allgemeine Anforderungen und Prüfungen
Sécurité des machines - Équipements de protection électrosensibles - Partie 1: Exigences générales et essais
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
