| scope | 1.1 These test methods cover solventless varnishes used primarily as electrical, mechanical, and environmental protection for electrical equipment. 1.2 These 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 1.3 The values stated in inch-pound units are to be regarded as the standard. The values 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. 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. 1.5 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. | |
