Title
Standard Test Method for Colorfastness and Transfer of Color in the Washing of Leather
ASTM International
Publication Date:
Sep 10, 2000
Scope:
This test method covers the determination of the color-fastness of colored leathers, with or without a surface coating. The leathers to be tested are of the type normally expected to withstand frequent laundering. This test method also covers the simultaneous staining of adjacent textile materials when the leather specimens are washed. This test method does not apply to wet blue. Two procedures are covered depending on the apparatus used:
Procedure A, using the Launder-Ometer,2 and
Procedure B, using an alternative washing machine.
The values stated in inch-pound units are to be regarded as the standard. The values stated in parentheses are provided for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
2 The Launder-Ometer and its development are described in the American Dyestuff Reporter, Oct. 29, 1928, p. 679. It is described also in the current Technical Manual of the American Association of Textile Chemists and Colorists. The Launder-Ometer is manufactured by Atlas Electric Devices Co., 4114 N. Ravenswood Ave., Chicago, IL 60613; telephone: (773) 327-4520; fax: (773) 327-5787. Such an apparatus is illustrated in Figs. 3, 4, and 5.
