1.1 本指南为测量洗涤剂防止污垢从洗涤剂溶液沉积到织物上的能力提供了指导。它旨在作为一种实验室筛选测试，有助于洗涤剂产品的配方、质量控制，并作为买方和卖方之间标准化特定产品性能的基础。 1.2 洗涤剂产品的抗土壤沉积性能将因测试中使用的土壤和织物的类型而异。因此，土壤、织物、参考洗涤剂和试验条件的选择应由相关方根据经验协商决定。 1.3 没有单一或组合的油性土壤或颗粒性土壤，或两者都能准确预测产品或处理在消费者感知的抗再沉积方面的整体性能。本指南旨在评估或比较抗- 所选特定土壤的再沉积性能。 1.4 以英寸磅或国际单位制表示的数值应单独视为标准。括号中给出的值仅供参考。 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。 提供试剂和材料的材料安全数据表。在使用前对其进行危险性审查。 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 该指南可用于比较产品的防再沉积性能；然而，这种受控的实验室技术与消费者的抗再沉积性能排名之间的相关性并没有得到证实的依据。

1.1 This guide provides direction for measuring the ability of detergents to prevent the deposition of soils from detergent solutions onto fabrics. It is intended as a laboratory screening test to aid in the formulation of detergent products, for quality control, and as a basis between the purchaser and seller in standardizing specific products' performance. 1.2 The anti-soil deposition performance of detergent products will vary greatly depending on the type of soils and fabrics used in the test. Therefore, selection of the soils, fabrics, reference detergents, and test conditions shall be made by agreement between the interested parties on the basis of experience. 1.3 There is no single or combination of oily soils or particulate soils, or both, that will precisely predict overall the performance of a product or treatment with respect to anti-redeposition as perceived by a consumer. This guide is intended to assess or compare detergent performance with respect to the anti-redeposition performance for the specific soil chosen. 1.4 The values stated in either inch-pound or SI units are to be regarded separately as the standard. The values given in parentheses are for information only. 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. Material safety data sheets are available for reagents and materials. Review them for hazards prior to usage. 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 The guide can be used to compare anti-redeposition performance of products; however, there is no confirmed basis for correlation of this controlled laboratory technique with consumers’ ranking of anti-redeposition performance.
