Significance and Use

The test methods referenced in these test methods are useful for control purposes during the manufacture and use of solventless varnishes.

1. 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 or other certain pressure), spraying, or brushing for the purpose of impregnating or sealing electrical equipment. The following test methods are included:

Property Tests (Uncured):	Section
Density
Flash Point
Gel Time
Monomer Content
Rheological Properties (Non-Newtonian)
Brookfield Viscosity
Performance Property Tests (cured):
Bond Strength
Coating Thickness
Dielectric Strength
Dielectric Strength-Using Metal Panels
Permittivity and Dissipation Factor
Build

1.3 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.

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. Specific hazard statements are given in 8.3, 15.5.1, and 15.5.2.
