This test method is useful for the evaluation of insulating varnish performance in chemical exposure.

1. Scope

1.1 This test method covers the mechanical performance of insulating varnishes after exposure to various chemicals.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 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. See 7.1.

Note 1—There is no IEC/ISO equivalent.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
