4.1 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, and4.1.4 Nonvolatile matter by weight.4.2 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, and4.2.8 Oil resistance.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 SectionBuild 38 – 42Dielectric Strength 43 – 48Drainage 26 – 32Flash Point 18 – 20Nonvolatile Matter 21 – 25Oil Resistance 54 – 56Preparation of Test Specimens 7Specific Gravity 9 – 12Temperature Index 49 – 50Time of Drying 33 – 37Varnish Compatibility 51 – 53Viscosity 13 – 171.2 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 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, health, and environmental 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.1.5 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.
