ASTM D2096-11

Standard Test Method for Colorfastness and Transfer of Color in the Washing of Leather

SIGNIFICANCE AND USE
The procedure is intended, primarily to evaluate the ability of a leather specimen to withstand fixed, and rather strenuous, laundering conditions. This test is not intended as a recommended washing procedure, neither household nor commercial. Although this test concerns itself with colorfastness and transfer of color during washing, the washed leather specimens are available also for comparing other properties (that is, tensile strength, area change, change in outline, etc.) with those of unwashed samples.
SCOPE
1.1 This test method covers the determination of the colorfastness 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:
1.1.1 Procedure A,  using the Launder-Ometer, and
1.1.2 Procedure B,  using an alternative washing machine.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values stated in parentheses are provided 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 and health practices and determine the applicability of regulatory limitations prior to use.
