EN 60445:2010

Basic and safety principles for man-machine interface, marking and identification - Identification of equipment terminals, conductor terminations and conductors

IEC 60445:2010 applies to the identification and marking of terminals of electrical equipment such as resistors, fuses, relays, contactors, transformers, rotating machines and, wherever applicable, to combinations of such equipment (e.g. assemblies), and also applies to the identification of terminations of certain designated conductors. It also provides general rules for the use of certain colours or alphanumeric notations to identify conductors with the aim of avoiding ambiguity and ensuring safe operation. These conductor colours or alphanumeric notations are intended to be applied in cables or cores, busbars, electrical equipment and installations. This fifth edition is a merged version of IEC 60445 and IEC 60446, and cancels and replaces the fourth edition of IEC 60445, published in 2006, and the fourth edition of IEC 60446, published in 2007. It has the status of a basic safety publication in accordance with IEC Guide 104. This edition includes the following significant technical changes with respect to the previous edition: - addition of new definitions in Clause 3; - revision of some clauses to use words from reference IEC standards. These revisions did not change any technical requirements but to clarify the wording; - addition of Annex B (informative) 'List of notes concerning certain countries'.

Principes fondamentaux et de sécurité pour les interfaces homme-machines, le marquage et l'identification - Identification des bornes de matériels, des extrémités de conducteurs et des conducteurs

La CEI 60445:2010 s'applique à l'identification et au marquage des bornes de matériels électriques, tels que résistances, coupe-circuits à fusibles, relais, contacteurs, transformateurs, machines tournantes et, chaque fois que cela est possible, à des combinaisons de tels matériels (par exemple des ensembles) et s'applique aussi à l'identification des extrémités de certains conducteurs désignés. Elle prévoit également des règles générales concernant l'utilisation de certaines couleurs ou de certains caractères alphanumériques pour identifier les conducteurs dans le but d'éviter toute ambiguïté et de garantir la sécurité de fonctionnement. Ces couleurs ou ces caractères alphanumériques destinés aux conducteurs doivent être appliqués aux câbles ou aux noyaux, aux barres omnibus, aux matériels et aux installations électriques. Cette cinquième édition qui fusionne la CEI 60445 et la CEI 60446, annule et remplace la quatrième édition de la CEI 60445, publiée en 2006, et la quatrième édition de la CEI 60446, publiée en 2007. Elle a le statut d'une publication fondamentale de sécurité, conformément au Guide 104 de la CEI. Cette édition inclut les modifications techniques importantes suivantes par rapport à l'édition précédente: - l'adjonction de nouvelles définitions à l'Article 3; - la révision de certains articles afin d'utiliser la terminologie des normes CEI de référence. Ces révisions ne modifient aucune exigence technique, mais en clarifient la formulation; - l'adjonction de l'Annexe B (informative) 'Liste des notes concernant certains pays'.

Osnovna in varnostna načela za vmesnik človek-stroj, označevanje in razpoznavanje - Razpoznavanje terminalov opreme, končnikov vodnikov in vodnikov (IEC 60445:2010)

Ta mednarodni standard velja za identifikacijo in označevanje terminalov električne opreme, kot so upori, varovalke, releji, vtikala, transformatorji, rotacijski stroji in, če je primerno, za kombinacije te opreme (npr. sklope); velja tudi za razpoznavanje končnikov določenih vodnikov. Prav tako zagotavlja splošna pravila za uporabo določenih barv ali alfanumeričnih oznak za razpoznavanje vodnikov s ciljem izogniti se nejasnosti in zagotoviti varno delovanje. Te barve vodnikov ali alfanumeričnih oznak so namenjene uporabi v kablih ali sredicah, zbiralkah, električni opremi in inštalacijah.

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
agreemen
