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

NEW!IEC 60445:2017 is available as IEC 60445:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60445:2017 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 basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It has the status of a basic safety publication in accordance with IEC Guide 104.This sixth edition cancels and replaces the fifth edition of IEC 60445, published in 2010. This edition includes the following significant technical changes with respect to the previous edition: a) the text of the introduction has been moved into the scope in accordance with IEC Guide 104; b) colour codes for the identification of line conductors of DC systems; c) colour code for the identification of functional earthing conductor; d) update of Table A.1with colour codes for DC line conductors; e) conversion of notes containing non-mandatory requirements to normative text; f) the terminology is aligned with IEC 60050-195.

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

NEW!IEC 60445:2017 est disponible sous forme de IEC 60445:2017 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60445:2017 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. Il 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. Elle a le statut d'une publication fondamentale de sécurité, conformément au Guide 104 de l’IEC. Cette sixième édition annule et remplace la cinquième édition de l’IEC 60445, parue en 2010. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a) le texte de l’introduction a été déplacé dans le domaine d’application conformément au Guide 104 de l’IEC; b) codes couleur permettant l’identification des conducteurs de ligne dans les systèmes à courant continu; c) code couleur permettant l’identification d’un conducteur de mise à la terre fonctionnelle; d) mise à jour du Tableau A.1intégrant les codes couleur des conducteurs de ligne à courant continu; e) conversion des notes comportant des exigences non obligatoires en texte normatif; f) la terminologie est alignée sur l’IEC 60050-195.

Osnovna in varnostna načela za vmesnik človek-stroj, označevanje in razpoznavanje - Razpoznavanje terminalov opreme, končnikov vodnikov in vodnikov

Ta dokument se uporablja za razpoznavanje in označevanje terminalov električne opreme, kot so upori, varovalke, releji, kontaktorji, transformatorji, motorji in, kadar je to primerno, za kombinacije takšne opreme (npr. sklope). Uporablja se tudi za razpoznavanje končnikov nekaterih navedenih vodnikov. Določa tudi splošna pravila za uporabo nekaterih barv ali alfanumeričnih oznak za razpoznavanje vodnikov, ki preprečujejo dvoumnost in zagotavljajo varno delovanje. Te barve vodnikov ali alfanumerične oznake so namenjene za uporabo na kablih ali jedrih, vodilih, električni opremi in napravah.
Ta osnovna varnostna publikacija je namenjena predvsem tehničnim odborom za pripravo standardov v skladu z načeli vodil IEC 104 in ISO/IEC 51.
Ni namenjena proizvajalcem ali certifikacijskim organom. Ena od pristojnosti tehničnih odborov je, da med pripravo publikacij uporabljajo osnovne varnostne publikacije, kadar je to primerno. Zahteve te osnovne varnostne publikacije se ne uporabljajo, razen če so izrecno navedene ali zajete v ustreznih publikacijah.

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 c
