    Scope - (Show below) - (Hide below)

    1.1This specification covers the tests and values for electrical insulating varnishes, as supplied, which are suitable for the impregnation and treatment of electrical coils and windings applied by dip process.

    1.2Varnishes, flexible or rigid, included in this specification are:

    Grade DA—Air-dry

    Grade DO—Organic solvent containing, baking,

    Grade DM—Reactive diluent containing,

    Grade DS—Silicone,

    Grade DW—Water containing, and

    Grade DT—Thixotropic.

    1.3The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    Note 1—This specification resembles IEC 60455 in title only. The content is significantly different.
