Safety of machinery - Electro-sensitive protective equipment - Part 1: General requirements and tests

IEC 61496-1:2012 specifies general requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons 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 may include optional safety-related functions, the requirements for which are given in Annex A. This third edition cancels and replaces the second edition published in 2004 and its amendment 1 (2007). The main changes with respect to the previous edition are as follows: The design, test and verification requirements have been updated to make them consistent with the latest standards for functional safety and EMC.

Sicherheit von Maschinen - Berührungslos wirkende Schutzeinrichtungen - Teil 1: Allgemeine Anforderungen und Prüfungen

Sécurité des machines - Equipements de protection électro-sensibles - Partie 1: Prescriptions générales et essais

La CEI 61496-1:2012 définit les prescriptions générales de conception, de construction et d'essai des équipements de protection électro-sensibles (ESPE) sans contact spécifiquement conçus pour détecter des personnes au sein d'un système relatif à la sécurité. Une attention particulière est portée sur les prescriptions de fonctionnement et de conception assurant que le niveau de sécurité approprié est atteint. Un ESPE peut proposer des fonctions optionnelles, liées à la sécurité: les prescriptions pour celles-ci sont énumérées en Annexe A. Cette troisième édition de la CEI 61496-1 annule et remplace la deuxième édition parue en 2004 et son amendement 1 (2007). Par rapport à l'édition précédente, les changements majeurs sont les suivants: les exigences de conception, d'essai et de vérification ont été mises à jour pour les rendre cohérentes avec les normes les plus récentes relatives à la sécurité fonctionnelle et à la CEM (compatibilité électromagnétique).
