Scope

Values obtained by flexural test can provide information with regard to the bond strength of the particular varnish in combination with a particular type of magnet wire, when measured under conditions described in this test method.

1.1 This 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.

1.2 This standard does not purport to address all, if any, 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. A specific precautionary statement is given in Section 7.

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

Note 18212;Although this standard and Method C of IEC 61033 differ in approach or detail, data obtained using either are technically equivalent.
