CONTAINED IN VOL. 10.02, 2017 Describes the determination of the bond strength of an electrical insulating varnish when applied to a twisted coil of film-insulated magnet wire.

1.1This test method covers the determination of the bond strength of an electrical insulating varnish when applied to a twisted coil of film-insulated magnet wire. The use of a particular type of film-insulated wire will show the values for that combination of film coating and varnish.

1.2The values stated in inch-pound units are the standard. The values given in parentheses are for information only.

Note 1:Although this standard and Method C of IEC 61033 differ in approach or detail, data obtained using either are technically equivalent.

1.3This 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. A specific precautionary statement is given in Section 7.

1.4This 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.
