ASTM D1932-19(Test Method)
Standard Test Method for Thermal Endurance of Flexible Electrical Insulating Varnishes

SIGNIFICANCE AND USE
5.1 A major factor affecting the long term performance of insulating materials is thermal degradation. It is possible that factors, such as moisture and vibration, will cause failures after the material has been weakened by thermal degradation.  
5.2 An electrical insulating varnish is effective in protecting electrical equipment only as long as it retains its physical and electrical integrity.  
5.3 The thermal degradation of the varnish results in weight loss, porosity, crazing, and generally a reduction in flexibility. Degradation of the varnish can be detected by a decrease in dielectric strength, which is therefore used as the failure criterion for this test method.  
5.4 Electrical insulating varnishes undergo flexing in service due to vibration and thermal expansion. For this reason, this functional test includes flexing and elongation of the insulation. The electrodes used in this test method are designed to elongate the outer surface of the specimen 2 % with respect to the neutral axis of the base fiber while being tested for dielectric breakdown.
SCOPE
1.1 This test method covers the determination of the relative thermal endurance of flexible electrical insulating varnishes by determining the time necessary at elevated temperatures to decrease the dielectric breakdown of the varnish to an arbitrarily selected value when applied to a standard glass fiber fabric.  
1.2 This test method does not apply to varnishes that lose a high percentage of their dielectric breakdown voltage when flexed before elevated temperature exposure as prescribed in the screening test (Section 9). Examples of such varnishes are those used for high speed armatures and laminated structures. Also, this test method is not applicable to varnishes which distort sufficiently during thermal elevated temperature exposure so that they cannot be tested using the curved electrode assembly.  
1.3 Thermal endurance is expressed in terms of a temperature index.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
Note 1: There is no equivalent IEC or ISO standard.  
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 7.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Determination of Volatile Organic Compound (VOC) Content of Electrical Insulating Varnishes

SIGNIFICANCE AND USE
4.1 This test method determines the volatile organic content of an electrical insulating varnish. It utilizes a procedure where dishes containing a known amount of varnish are baked and the amount of volatile organic compound is measured. Calculations are performed to express this in g/L or lb/gal. This test method is applicable to all types of varnishes. However, waterborne varnishes while baked under the same conditions need to have water content determined and calculations performed in accordance with Practice D3960.  
4.1.1 During the cure of electrical insulating varnishes some organic material is volatilized. A determination of the amount that is volatilized is useful for estimating the amount of cured varnish on electrical units and volatile organic emissions from a manufacturing facility.
SCOPE
1.1 This test method covers the determination of the amount of volatile organic compounds emitted during cure of electrical insulating varnishes.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.  
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
