Description / Abstract:

This specification covers the requirements and methods of test for three types and four grades of orange shellac and other lacs, typically used as bonding agents for mica splittings and reconstituted mica paper and as coating for other materials, as follows:

Type I—Orange Flake Shellac, Grades A, B, C, and D,

Type II—Button Lac, and

Type III—Garnet Lac.

Stick-lac and seed-lac are not covered by this specification.

NOTE 1—ISO Specifications 56–1 and 56–2 cover shellac. However, the equivalency of the ISO specification to this standard is unknown. Refer directly to the ISO standards to determine equivalency.

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

*A Summary of Changes section appears at the end of this standard.
