1.1 本试验方法仅涵盖在规定条件下进行试验时，用于确定家用/商用真空吸尘器的相对地毯污垢清除效果的实验室试验。 1.2 本试验方法适用于家用/商用立式、筒式和组合式清洁剂。 1.3 本试验方法适用于去除地毯上的嵌入污垢，而不是去除表面垃圾和碎屑。 注1: F11.21小组委员会正在地毯行业的协助下，积极寻求与新市场相关的地毯。尽管毛绒和Frieze地毯面板不再可供购买，但一些实验室可能仍有样品可供测试。 在这种情况下，表值仍然有效。 注2: 由于环境条件、时间变化、测试材料来源和操作员熟练程度的影响，当在同一实验室同时对多个电器进行比较测试时，大多数描述的测试方法将给出更可靠的结果，并由同一操作员进行，直到完成新的实验室间研究以提供重复性和再现性值。 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。 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====== 4.1 该测试方法提供了真空吸尘器清除地毯上嵌入污垢的能力指示。这种测试方法基于家庭清洁测试的结果，因此在大多数情况下，家庭和实验室结果之间存在合理的相关性。实验室测试中收集的污垢数量可能与家中的不同；然而，它将表明，在大多数情况下，在实验室表现良好的真空吸尘器在家中也会表现良好。由于房屋、地毯、污垢和其他因素的不同，实验室结果可能会有所不同（见第节 6. ). 4.2 为了为测量中所述的性能提供统一的基础 1.1 ，标准化测试地毯和标准化测试污垢被用于该程序中。

1.1 This test method covers only a laboratory test for determining the relative carpet dirt removal effectiveness of household/commercial vacuum cleaners when tested under specified conditions. 1.2 This test method is applicable to household/commercial types of upright, canister, and combination cleaners. 1.3 The test method applies to embedded dirt removal from carpets, not the removal of surface litter and debris. Note 1: The F11.21 subcommittee is actively pursuing new market relevant carpets with the assistance of the carpet industry. Although plush and Frieze carpet panels are no longer available for purchase, some laboratories may still have samples for testing. In such cases, the table values remain valid. Note 2: Due to the influence of environmental conditions, variations in time, origin of test materials, and proficiency of the operator, most of the described test methods will give more reliable results when applied for comparative testing of a number of appliances at the same time, in the same laboratory, and by the same operator until a new interlaboratory study has been completed to provide repeatability and reproducibility values. 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. 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 ====== 4.1 This test method provides an indication of the capability of the vacuum cleaner to remove embedded dirt from carpeting. This test method is based upon results of home cleaning tests so that, in most cases, a reasonable correlation exists between home and laboratory results. The amount of dirt picked up in the laboratory test may not be the same as in the home; however, it will show that, in most cases, a vacuum cleaner that performs well in the laboratory will perform well in a home. Laboratory results may differ due to variations in the homes, carpets, dirt, and other factors (see Section 6 ). 4.2 In order to provide a uniform basis for measuring the performance described in 1.1 , standardized test carpets and a standardized test dirt are employed in this procedure.
