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:

Procedure Section Build 37 to 41 Dielectric Strength 42 to 47 Drainage 25 to 31 Flash Point 17 to 19 Nonvolatile Matter 20 to 24 Oil Resistance 53 to 55 Preparation of Test Specimens 7 Specific Gravity 9 to 12 Temperature Index 48 to 49 Time of Drying 32 to 36 Varnish Compatibility 50 to 52 Viscosity 13 to 16

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.

1.4 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.
