1.1These test methods cover solventless varnishes used primarily as electrical, mechanical, and environmental protection for electrical equipment.
1.2These test methods are used on solventless varnishes that are applied by dipping (at atmospheric pressure conditions or under vacuum followed by pressure or under pressure only), spraying, or brushing for the purpose of impregnating or sealing electrical equipment. The following test methods are included:
| Property Tests (Uncured): | Section |
| Density | 7 |
| Flash Point | 8 |
| Gel Time | 9 |
| Monomer Content | 10 |
| Rheological Properties (Non-Newtonian) | 11 |
| Rotational Viscosity | 12 |
| Performance Property Tests (cured): | |
| Bond Strength | 13 |
| Coating Thickness | 14 |
| Dielectric Strength | 15 |
| Dielectric Strength-Using Metal Panels | 16 |
| Permittivity and Dissipation Factor | 17 |
| Build | 18 |
1.3The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.
1.4This 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. Specific hazard statements are given in 8.3, 15.5.1, and 15.5.2.
Note 1:This test method is related to IEC 60455. Since both methods contain multiple test procedures, many procedures are technically equivalent while others differ significantly.
1.5This 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.
