1.1 本试验方法涵盖有或无表面涂层的有色皮革色牢度的测定。要测试的皮革是通常预期能够承受频繁洗涤的类型。本试验方法还涵盖了在清洗皮革样本时相邻纺织材料的同时染色。本试验方法不适用于蓝湿革。根据使用的仪器，涵盖两个程序: 1.1.1 程序A， 使用流槽流量计， 2. 和 1.1.2 程序B， 使用替代洗衣机。 1.2 以英寸-磅为单位的数值应视为标准值。 括号中的数值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 该程序主要用于评估皮革样本承受固定且相当剧烈的洗涤条件的能力。无论是家用还是商用，本试验均不作为推荐的洗涤程序。虽然本试验涉及染色牢度和洗涤过程中的颜色转移，但洗涤后的皮革样品也可用于与未洗涤样品的其他性能（即拉伸强度、面积变化、轮廓变化等）进行比较。

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, 2 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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. ====== Significance And Use ====== 4.1 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.
