BS EN 60085:2008 - Electrical insulation. Thermal evaluation and designation

BS EN 60085:2008

Electrical insulation. Thermal evaluation and designation

Status : Current   Published : March 2009



IEC 60085:2007 now distinguishes between thermal classes for electrical insulation systems and electrical insulating materials. It establishes the criteria for evaluating the thermal endurance of either electrical insulating materials (EIM) or electrical insulation systems (EIS). It also establishes the procedure for assigning thermal classes. This standard is applicable where the thermal factor is the dominant ageing factor. The major technical changes with regard to the previous edition concern the fact that this edition is an amalgamation of the third edition of this standard together with IEC 62114:2001. It has the status of a horizontal standard in accordance with

IEC Guide 108
