1.1 本试验方法包括在施加表面摩擦后，测量编织布中一组纱线相对于另一组纱线的纱线变形。本试验方法特别适用于开口织物，如网布、纱布、薄纱、雪纺和由光滑表面纱线制成的较重织物。 注1: 关于机织物中纱线滑移的测定，请参阅试验方法 D434页 . 1.2 以国际单位制表示的数值应视为标准。括号中给出的英寸-磅单位仅供参考。 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====== 5.1 由于目前实验室间精度的估计值是可接受的，并且该方法已在验收测试行业中广泛使用，因此该测试方法被认为适合于商业装运的验收测试。 5.2 如有争议，应确定买方实验室和卖方实验室之间的统计偏差（如有），每次比较均基于对一个织物样品的随机样本进行测试。 5.3 本试验方法用于指示纱线在织物中移动或变形的倾向。 由于由此产生的外观变化，这种扭曲是令人反感的。这些外观变化有时被称为“指印”或“移位标记” 5.4 根据材料的预期用途，建议在原始条件下以及在洗涤或干洗或两者兼有后对织物进行测试。

1.1 This test method covers the measurement of yarn distortion of one set of yarns over the other in woven cloth following the application of surface friction. This test method especially is applicable to open-weave fabrics, such as nettings, marquisettes, gauzes, chiffons, and heavier fabrics made from slippery surface yarns. Note 1: For the determination of yarn slippage in woven fabrics, refer to Test Method D434 . 1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given 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 ====== 5.1 This test method is considered satisfactory for acceptance testing of commercial shipments because current estimates of between-laboratory precision are acceptable and the method has been used extensively in the trade for acceptance testing. 5.2 In cases of dispute, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the seller should be determined, with each comparison being based on testing randomized specimens from one sample of fabric. 5.3 This test method is used as an indication of the propensity of yarns to shift or distort in a fabric. Such distortions are objectionable due to the resulting changes in appearance. These appearance changes are sometimes referred to as “finger marks” or “shift marks.” 5.4 It is recommended that fabrics be tested in their original condition and also after laundering or drycleaning, or both, depending upon the intended use of the material.
