Standard Test Methods for Testing Solvent Containing Varnishes Used for Electrical Insulation
The following bibliographic material is provided to assist you with your purchasing decision:
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:
| Procedure | Section |
| Build | 38 – 42 |
| Dielectric Strength | 43 – 48 |
| Drainage | 26 – 32 |
| Flash Point | 18 – 20 |
| Nonvolatile Matter | 21 – 25 |
| Oil Resistance | 54 – 56 |
| Preparation of Test Specimens | 7 |
| Specific Gravity | 9 – 12 |
| Temperature Index | 49 – 50 |
| Time of Drying | 33 – 37 |
| Varnish Compatibility | 51 – 53 |
| Viscosity | 13 – 17 |
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 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.
Significance and Use
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, and
4.1.4 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, and
4.2.8 Oil resistance.
