What is BS EN 60085 – Thermal evaluation of electrical insulation about?
BS EN 60085 is an International Standard which distinguishes between thermal classes for electrical insulation systems and electrical insulating materials. BS EN 60085 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.
BS EN 60085 is applicable where the thermal factor is the dominant ageing factor.
Note: A thermal class is not assigned to an EIM as related to its use in an EIS.
Who is BS EN 60085 - Thermal evaluation of electrical insulation for?
BS EN 60085 on thermal evaluation of EIM is relevant to:
- EIS manufacturers  
- Automotive industry 
- Electrical industry  
- Electrical engineers  
Why should you use BS EN 60085 - Thermal evaluation of Electrical insulation?
An electrical insulation system is comprised of a unique combination of materials that have been verified for chemical compatibility when used at certain maximum temperatures. In this regard, EIS insulating are structures containing one or more EIM together with associated conducting parts are employed in an electrotechnical device.
BS EN 60085 provides you general considerations and relation of EIM to EIS and specification on a thermal class assignment that ensures the performance of EIS.
BS EN 60085 covers the best industry EIS evaluation and provides guidance on three tests based on designed life to determine the thermal endurance and durability of the EIS. Thus, with minimized risk of breakdowns, you can maintain the overall integrity and operational efficiency of EIS.
