ASTM D115 Standard Test Methods for Testing Solvent Containing Varnishes Used for Electrical Insulation
ASTM D115电绝缘用含清漆试验溶剂的标准试验方法

Control—The following tests are useful for control purposes during the manufacture and use of varnishes, and for determining the uniformity of batches:
4.1.1 Specific gravity,
4.1.2 Viscosity,
4.1.3 Flash point, and
4.1.4 Nonvolatile matter by weight.
Performance—The following tests are useful for determining the performance of varnishes during application and use:
4.2.1 Drainage,
4.2.2 Time of drying,
4.2.3 Build,
4.2.4 Dielectric strength,
4.2.5 Thermal endurance,
4.2.6 Varnish compatibility,
4.2.7 Salt water proofness, and
4.2.8 Oil resistance.

1. Scope
1.1 These test methods cover tests for solvent containing varnishes primarily intended to provide electrical, mechanical, and chemical protection for electrical equipment. These test methods include tests for control and performance as follows:
1.2 Where the entire test method is included in this standard, the precision and bias are not known unless given in the stated method.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 hazard statements, see Section 5.
Note 1
There is no equivalent IEC standard.
