1.1 This specification covers shellac varnish consisting of a solution or “cut” of a specified type and grade of dry lac resin in specially denatured alcohol. Ninety-five percent (190 proof) ethyl alcohol, specially denatured according to Formula No. 1 of the Alcohol, Tobacco, and Firearms of the Treasury Dept., is the solvent most commonly used. However, other specially denatured alcohols and proprietary solvents are also used for this purpose.1.2 The 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.1.3 This 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.

This 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. The varnishes are classified according to grades: Grade DA; Grade DO; Grade DM; Grade DS; Grade DW; and Grade DT. This specification covers both flexible and rigid, solvent and solventless insulating varnishes. The insulating varnishes are classified according to thermal classes: Class 130; Class 155; Class 180; Class 200; and Class 220. Quality conformance tests shall be performed to conform to the specified requirements.1.1 This 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.1.2 Varnishes, flexible or rigid, included in this specification are:Grade DA—Air-dryGrade DO—Organic solvent containing, baking,Grade DM—Reactive diluent containing,Grade DS—Silicone,Grade DW—Water containing, andGrade DT—Thixotropic.1.3 The 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.1.4 This 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.

2.1 These test methods are applicable to varnish and are useful to producers and users in determining nonvolatile content and are sometimes an appropriate measure of the film-forming matter in varnish.1.1 These test methods determine the fraction of a varnish that is nonvolatile at the temperature of the test while volatile solvents are driven off. It is sometimes an approximate measure of the film-forming matter in a varnish.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific statement, see Section 3.1.4 This 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.
