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:
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 and health practices and determine
the applicability of regulatory limitations prior to use.
