Safety of machinery - Application of protective equipment to detect the presence of persons (IEC 62046:2018)

This International Standard 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.

Sécurité des machines - Application des équipements de protection à la détection de la présence de personnes (IEC 62046:2018)

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.

Varnost strojev - Uporaba zaščitne opreme za zaznavanje prisotnosti oseb (IEC 62046:2018)

Ta mednarodni standard določa zahteve za izbiro, postavitev, konfiguracijo in usposabljanje za zagon zaščitne opreme za zaznavanje začasne ali neprekinjene prisotnosti oseb z namenom zaščite teh oseb pred nevarnimi deli strojev v industrijski uporabi. Ta standard obravnava uporabo električno občutljive varovalne opreme (ESPE) iz standarda IEC 61496 (vsi deli) ter preprog in podov, občutljivih na tlak, iz standarda ISO 13856-1.
Upošteva lastnosti strojev, varovalne opreme, okolja in človeške komunikacije oseb, starejših od 14 let. Ta dokument vključuje informativne dodatke, ki podajajo navodila o uporabi zaščitne opreme za zaznavanje prisotnosti oseb. Ti dodatki vsebujejo primere, na podlagi katerih so predstavljena načela tega standarda. Namen teh primerov ni podati edino rešitev za določeno uporabo ter omejevati inovativnost ali tehnološki napredek. Primeri predstavljajo le rešitve, ki prikazujejo določene koncepte vgradnje zaščitne opreme, in so bili poenostavljeni za boljše razumevanje, zato so morda nepopolni.

SAFETY OF MACHINERY – APPLICATION OF PROTECTIVE
EQUIPMENT TO DETECT THE PRESENCE OF PERSONS

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible

SAFETY OF MACHINERY – APPLICATION OF PROTECTIVE
EQUIPMENT TO DETECT THE PRESENCE OF PERSONS

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of
