The object of this standard is to specify 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 applies to empty enclosures, prior to the incorporation of switchgear and controlgear components by the user, as supplied by the enclosure manufacturer. This standard does not apply to enclosures which are covered by other specific products standards (e.g. IEC 60670, household and similar installations). Compliance with the safety requirements of the applicable product standard is the responsibility of the final assembly manufacturer. This standard may serve as a basis for other technical committees
