1.1 本测试方法仅提供了一种实验室测试，用于在标准条件下测试时，直观地确定湿提取清洁系统的相对地毯清洁效果。 1.2 本试验方法适用于立式、罐式和组合式湿提取清洁剂及其推荐的化学清洁配方，用于清洁地毯作为主要或次要功能。本试验方法不包括预喷涂系统或预喷涂处理。 1.3 本试验方法不适用于室内装潢清洁或裸露地板清洁。 1.4 本试验方法仅适用于清洁地毯上的嵌入土壤，不适用于清除表面垃圾和碎屑。 1.5 该试验方法不直接量化去除的土壤量，而是通过使用比色仪器进行目视评估。 1.6 单位-- 以国际单位制或英寸-磅单位表示的值应单独视为标准值。每个系统中所述的值可能不是完全等效的；因此，每个系统都应独立使用。 将两个系统的值结合起来可能会导致不符合标准。 1.7 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.8 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====== 4.1 该测试方法将指示清洁系统在通过湿法提取清洁恢复人造污染地毯外观方面的有效性。由于房屋、地毯、土壤和其他因素的不同，实验室测试的清洁效果可能与家庭清洁不同。 4.2 为了为测量中描述的性能提供统一的基础 1.1 ，本程序采用标准化测试地毯、测试垫和测试土壤。

1.1 This test method provides only a laboratory test for visually determining the relative carpet cleaning effectiveness of a wet extraction cleaning system when tested under standard conditions. 1.2 This test method is applicable to types of upright, canister, and combination wet extraction cleaners and their recommended chemical cleaning formulas intended for cleaning carpets as a primary or secondary function. This test method excludes pre-spray systems or pre-spray treatments. 1.3 This test method is not applicable to upholstery cleaning or bare floor cleaning. 1.4 This test method applies only to the cleaning of embedded soil from carpet, not the removal of surface litter and debris. 1.5 This test method does not directly quantify the amount of soil removed but is visually assessed by employing colorimetric instrumentation. 1.6 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.7 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. 1.8 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 This test method will provide an indication of the effectiveness of the cleaning system at restoring the appearance of an artificially soiled carpet by wet extraction cleaning. The cleaning effectiveness in the laboratory test may not be the same as in home cleaning due to variations in the homes, carpets, soils, and other factors. 4.2 In order to provide a uniform basis for measuring the performance described in 1.1 , standardized test carpet, test pad, and test soil are employed in this procedure.
