1.1 当在规定的测试条件下进行测试时，本测试方法仅提供用于确定家用/商用真空吸尘器的相对硬表面地板清洁能力的实验室测试。 1.2 本试验方法适用于家用/商用立式、筒式、组合式和杆式真空吸尘器，这些吸尘器使用干燥的主要灰尘容器，并将清洁硬表面地板作为主要或次要功能。 1.3 本试验方法仅适用于清除硬表面地板上的干燥碎屑，而不适用于清除地毯上的嵌入污垢。 1.4 以英寸-磅单位表示的值应视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准值。 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。 1.6 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 该测试方法将提供真空吸尘器清除硬质表面地板上干燥碎屑的能力指示。 实验室测试中的清洁能力将与家庭清洁不同；然而，在大多数情况下，在实验室中表现良好的真空吸尘器在家中也能很好地清洁。 4.2 为测量中所述的性能提供统一的基础 1.1 使用标准化测试硬表面地板和标准化测试碎片。

1.1 This test method provides only a laboratory test for determining the relative hard surface floor-cleaning ability of household/commercial vacuum cleaners when tested under specified test conditions. 1.2 This test method is applicable to household/commercial types of upright, canister, combination, and stick vacuum cleaners that use a dry primary dirt receptacle and are intended for cleaning hard surface floors as a primary or secondary function. 1.3 This test method applies only to the removal of dry debris from hard surface floors, not the removal of embedded dirt from carpet. 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 will provide an indication of the ability of the vacuum cleaner in removing dry debris from hard surface floors. The cleaning ability in the laboratory test will not be the same as in home cleaning; however, in most cases, a vacuum cleaner that performs well in the laboratory will clean well in a home. 4.2 To provide a uniform basis for measuring the performance described in 1.1 , standardized test hard surface flooring and standardized test debris are used.
