(Main)Empty enclosures for low-voltage switchgear and controlgear assemblies - General requirements
Empty enclosures for low-voltage switchgear and controlgear assemblies - General requirements
Applies to empty enclosures, prior to the incorporation of switchgear and controlgear components by the user, as supplied by the enclosure manufacturer. This standard specifies definitions, classifications, characteristics and test requirements of enclosures to be used as part of switchgear and controlgear assemblies in accordance with the EN 60439 series, the rated voltage of which does not exceed 1 000 V a.c. at frequencies not exceeding 1 000 Hz, or 1 500 V d.c. and suitable for general use for either indoor or outdoor applications. This standard does not apply to enclosures, which are covered by other specific products standards (e.g. EN 60670). Compliance with the safety requirements of the applicable product standard is the responsibility of the final assembly manufacturer.

Enveloppes vides destinées aux ensembles d'appareillage à basse tension - Règles générales
S'applique aux enveloppes vides, avant incorporation de l'appareillage par l'utilisateur, dans l'état où elles sont fournies par le constructeur. Cette norme spécifie les définitions, les classifications, les caractéristiques et les exigences d'essais des enveloppes à utiliser en tant que partie d'ensembles d'appareillage selon la série EN 60439, dont la tension assignée ne dépasse pas 1 000 V en courant alternatif à des fréquences ne dépassant pas 1 000 Hz, ou 1 500 V en courant continu pour usage général extérieur ou intérieur. Cette norme ne s'applique pas aux enveloppes qui sont couvertes par d'autres normes de produits spécifiques (par exemple la EN 60670). La conformité avec les prescriptions de sécurité de la norme de produit applicable est de la responsabilité du constructeur final de l'ensemble.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governme
