BSI BS EN 61857-1:2005

Electrical insulation systems. Procedures for thermal evaluation -- General requirements. Low-voltage

PUBLISH DATE 2005
PAGES 20
BSI BS EN 61857-1:2005
Specifies a general test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS) and establishes a procedure that compares the performance of a candidate EIS to that of a reference EIS. This basic standard is applicable to existing or proposed EIS used in electrotechnical products with an input voltage of up to 1 000 V where the thermal factor is the dominating ageing factor. This second edition cancels and replaces the first edition published in 1998, and constitutes a technical revision to make this basic standard compatible with parts 21 and 22.
