Boxes and enclosures for electrical accessories for household and similar fixed electrical installations - Part 1: General requirements

This part of EN 60670 applies to boxes, enclosures and parts of enclosures (hereafter called boxes and enclosures) for electrical accessories with a rated voltage not exceeding 1 000 V a.c. and 1 500 V d.c. intended for household or similar fixed electrical installations, either indoors or outdoors. This edition cancels and replaces the second edition of EN 60670 published in 1989 and its amendment 1 (1994). This edition constitutes a technical revision.

Dosen und Gehäuse für Installationsgeräte für Haushalt und ähnliche ortsfeste elektrische Installationen - Teil 1: Allgemeine Anforderungen

Boîtes et enveloppes pour appareillage électrique pour installations électriques fixes pour usages domestiques et analogues - Partie 1: Règles générales

La présente partie de la EN 60670 s'applique aux boîtes, parties d'enveloppes et enveloppes (ci-après désignées par les termes "boîtes" et "enveloppes") destinées à des appareillages électriques ayant une tension assignée ne dépassant pas 1 000 V alternatifs et 1 500 V continus prévus pour des installations électriques fixes à usages domestiques ou analogues, pour l'intérieur ou l'extérieur. Cette édition annule et remplace la deuxième édition de la EN 60670 parue en 1989 ainsi que son amendement 1 (1994). Cette édition constitue une révision technique.

Škatle in ohišja za električno opremo za gospodinjstvo in podobne nepremične električne inštalacije – 1. del: Splošne zahteve (IEC 60670-1:2002 + popravek 2003, spremenjen) (vsebuje popravek AC:2017 in popravek AC:2010)

Ta del standarda IEC 60670 se uporablja za škatle, ohišja in dele ohišij (v nadaljnjem besedilu »škatle« in »ohišja«) za električno opremo z nazivno napetostjo, ki ne presega izmenične napetosti 1000 V in enosmerne napetosti 1500 V in je namenjena uporabi v gospodinjstvu ali podobnih zunanjih ali notranjih nepremičnih električnih inštalacijah. OPOMBA Zahteve za posebne vrste škatel in ohišij so podane v ustreznih 2. delih standarda IEC 60670. Škatle in ohišja, ki so skladna s tem standardom, so primerna za uporabo pri temperaturi okolja, ki običajno ne presega 25 °C, vendar občasno lahko doseže 35 °C. Ta mednarodni standard je namenjen uporabi s škatlami in ohišji za električne pripomočke na področju uporabe tehničnega odbora IEC 23. OPOMBA Ta dokument se lahko uporablja kot referenčni dokument za druge tehnične odbore in pododbore IEC. Škatla ali ohišje, ki je sestavni del električne opreme in ji nudi zaščito pred zunanjimi vplivi (npr. mehanskim udarcem, vdorom trdnih predmetov ali vode itd.), je vključeno v ustrezni standard, ki obravnava tovrstno opremo.
Ta standard se ne uporablja za:
– stropne rozete;
– spojke za podporo svetilki;
– škatle, ohišja in dele ohišja, ki so izdelani posebej za uporabo s sistemi kabelskih korit in jaškov, ki so v skladu s standardom IEC 61084 in niso namenjeni namestitvi zunaj teh sistemov.
