ASTM D2756 Standard Test Method for Weight Loss of Electrical Insulating Varnishes
ASTM D2756 电绝缘清漆重量损失的标准测试方法

Weight loss is useful for indicating:
5.1.1 A form of degradation at elevated temperatures in air, and
5.1.2 Evolution of volatiles that have the potential to affect other components.

1. Scope
1.1 This test method covers the measurement of the loss in weight of cured electrical insulating varnishes on exposure to elevated temperature in air.
1.2 The values stated in SI units are the standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precaution statements, see Section 7.
Note 1
IEC 60216 Part 2 is technically equivalent to this standard.
