IEC 62046:2018

Safety of machinery - Application of protective equipment to detect the presence of persons

IEC 62046:2018 specifies requirements for the selection, positioning, configuration and commissioning of protective equipment to detect the momentary or continued presence of persons in order to protect those persons from dangerous part(s) of machinery in industrial applications. This standard covers the application of electro-sensitive protective equipment (ESPE) specified in IEC 61496 (all parts) and pressure sensitive mats and floors specified in ISO 13856-1.
It takes into account the characteristics of the machinery, the protective equipment, the environment and human interaction by persons of 14 years and older.
This document includes informative annexes to provide guidance on the application of protective equipment to detect the presence of persons. These annexes contain examples to illustrate the principles of this standard. These examples are not intended to be the only solutions to a given application and are not intended to restrict innovation or advancement of technology. The examples are provided only as representative solutions to illustrate some of the concepts of integration of protective equipment, and have been simplified for clarity, so they may be incomplete.
This first edition cancels and replaces IEC TS 62046, published in 2008. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC TS 62046:2008:
a) additional annexes relating to muting and vision systems,
b) muting requirements have been updated,
c) blanking requirements have been updated,
d) addition of IEC 61496 series Types and capping the Safety Integrity level according to IEC 62061 and performance levels according to ISO 13849-1,
e) alignment to changes in IEC 61496 series

Sécurité des machines - Application des équipements de protection à la détection de la présence de personnes

IEC 62046:2018 spécifie les exigences pour le choix, le positionnement, la configuration et la mise en service des équipements de protection prévus pour détecter la présence momentanée ou permanente de personnes afin de protéger celles-ci contre les parties dangereuses des machines dans des applications industrielles. Cette norme couvre l'application des équipements de protection électro-sensibles (ESPE) spécifiés dans l'IEC 61496 (toutes les parties) et les tapis et planchers sensibles à la pression spécifiés dans l'ISO 13856-1.
IEC 62046:2018 tient compte des caractéristiques des machines, des équipements de protection, de l'environnement et de l'interaction humaine par des personnes de 14 ans et plus.
IEC 62046:2018 inclut des annexes informatives qui fournissent des recommandations sur l'application de l'équipement de protection pour détecter la présence de personnes. Ces annexes contiennent des exemples présentant les principes de cette norme. Ces exemples ne sont pas réputés représenter des solutions uniques à une application donnée ni constituer une limitation à l'innovation ou aux avancées technologiques. Ces exemples sont donnés uniquement comme des solutions représentatives destinées à illustrer certaines des notions d'intégration d'équipements de protection et ont été simplifiés dans un but de clarification. De ce fait, ils peuvent être incomplets.
IEC 62046:2018 annule et remplace l'IEC TS 62046 parue en 2008. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC TS 62046:2008:
a) annexes supplémentaires relatives aux systèmes d'inhibition et de vision;
b) les exigences d'inhibition ont été mises à jour;
c) les exigences de blanking ont été mises à jour;
d) ajout des types de la série IEC 61496 et plafonnement du niveau d'intégrité de sécurité conformément à l'IEC 62061 et des niveaux de performance conformément à l'ISO 13849-1;
e) alignement sur les modifications apportées à la série IEC 61496.
