Scope

1.1 This test method is used to determine the amount of volatile organic compounds emitted during cure of electrical insulating varnishes.

1.2 The values stated in SI units are the 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 and health practices and determine the applicability of regulatory limitations prior to use. See Section 7 for specific precautions.

Significance and Use

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 D 3960.

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.
