Determination of temperature indices for electrical insulating varnishes

The purpose of the investigation, as pointed out, was to study varnishes as a component and to obtain temperature indices for different type varnishes. The Laboratory was also interested in establishing a basis for possible correlation between these methods and accelerated tests. With this investigation, additional data was made available which supplemented round robin data obtained by Subcommittee I of ASTM Committee D9 in its work on the weight loss technique for ASTM Test Method D115.
