(Main)Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-201: Particular requirements for control equipment
Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-201: Particular requirements for control equipment
IEC 61010-2-201:2017 specifies safety requirements and related verification tests for any product performing the function of control equipment and/or their associated peripherals. In addition, these products have as their intended use the command and control of machines, automated manufacturing and industrial processes, e.g. discrete and continuous control.
This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This second edition includes the following significant technical changes with respect to the previous edition;
a) clarify, change, delete definitions which were causing confusion,
b) change and clarify the temperature testing methodology,
c) change documentation methodologies allowed,
d) change some terminal markings,
e) add clarity to some of the informative annexes,
f) add Annex E with changes,
g) add Annexes AA – FF.
Exigences de securité pour appareils électriques de mesurage, de régulation et de laboratoire - Partie 2-201: Exigences particulières pour les équipements de commande
L'IEC 61010-2-201:2017 spécifie les exigences de sécurité et les essais de vérification associés pour les produits remplissant la fonction d'équipements de commande et/ou leurs périphériques associés. L'utilisation prévue de ces produits consiste à contrôler et commander les machines, les processus industriels et de fabrication automatisés, par exemple par le biais d'un contrôle discret et continu.
Cette deuxième édition annule et remplace la première édition parue en 2013. Cette édition constitue une révision technique.Cette deuxième édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) clarification, modification et suppression des définitions sources de confusion,
b) modification et clarification de la méthode d'essai des températures,
c) modification des méthodologies de documentation admises,
d) modification de quelques marquages de BORNES,
e) clarification de certaines annexes informatives,
f) ajout de l'Annexe E qui a elle-même fait l'objet de modifications,
g) ajout des Annexes AA à FF.
