Scope of standard

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.
