1.1 本规程涵盖了在实验室中贩运绒线地板覆盖物，以在受控条件下暴露于行人交通中，从而改变表面外观。一种单独的测试方法， D7330 ，涵盖了使用地毯和地毯协会参考量表对表面外观变化的评估。 2. 1.2 本规程适用于在所有类型的住宅或商业地毯中观察到的大多数表面外观变化。它通过关注毛面、平整或绒毛纤维配置变化引起的外观变化，消除了与污垢相关的外观变化。尽管“桩反转”或“水印”偶尔可见，但这种做法并不是产生这种现象的可靠方法。 1.3 买方和供应商可通过相互协议使用此做法来设置采购规范。 1.4 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 具体的预防说明见第节 7. . 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 通过暴露在足够的行人流量中，这种做法可以应用于任何表面外观发生变化的绒线地板覆盖物。 5.1.1 此做法不会模拟由于脏污、旋转或滚动交通或楼梯上的交通而导致的表面外观变化。

1.1 This practice covers the trafficking of pile yarn floor coverings in a laboratory in order to effect a change in surface appearance as a result of exposure to foot traffic under controlled conditions. A separate test method, D7330 , covers the assessment of surface appearance change using the Carpet and Rug Institute Reference Scales. 2 1.2 This practice is applicable to most changes in surface appearance observed in all types of carpet that are intended for residential or commercial use. It eliminates change in appearance associated with soiling by focusing on appearance change due to matting, flattening, or change in pile fiber configuration. Although “pile reversal” or “watermarking” is occasionally visible, this practice is not a reliable method for producing this phenomenon. 1.3 This practice may be used by mutual agreement between the purchaser and supplier to set purchasing specifications. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 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. Specific precautionary statements are given in Section 7 . 1.6 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 By exposure to sufficient foot traffic, this practice can be applied to any pile yarn floor covering which undergoes changes in surface appearance. 5.1.1 This practice does not simulate surface appearance changes due to soiling, pivoting, or rolling traffic, or traffic on stairs.
