This part of IEC 62271, which is a Technical Specification, applies to indoor enclosed switchgear and controlgear complying with IEC 62271-200 and IEC 62271-201, intended to be used in special service conditions with respect to condensation and pollution deviating from the normal service conditions specified in IEC 62271-1.

The test detailed in this document has been designed primarily to classify the electrical insulation performance of equipment having high-voltage electrical insulation exposed to indoor service conditions, mainly in presence of condensation. The assessment of mechanical components, such as mechanisms, interlocks and enclosure is also considered.

In this document, the term "equipment" is used in accordance with the scope for an "enclosed assembly of switchgear and controlgear" (see IEC 60050-441:2000, 441-12- 02).Cross References:IEC 62271-1:2017IEC 60060-1:2010IEC 62271-200IEC 62271-201IEC 60721-3-3IEC TS 60815-1IEC TR 60932IEC 60505 IEC 60507IEC 60068-2-78IEC 60721-2-5ISO 9223:2012IEC 60050-441:1984
