1.1 本试验方法包括在选定的典型地毯表面上前后移动立式、筒式、棒式或组合式真空吸尘器所需的相对功的测量。 1.1.1 此测试方法仅测量在地毯上移动真空吸尘器所需的水平功分量。 1.2 该测试方法可用于家用和商用吸尘器的测试。 1.3 此测试方法测量移动真空吸尘器及其运行中的一个或多个电机所需的相对功。 1.4 本试验方法仅适用于地毯的真空清洁。 1.5 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。 1.6 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。 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。部分 12 已被修改为删除不再可用的地毯（即毛绒、Frieze）。 1.7 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 该测试方法测量真空吸尘器在家中或标准化实验室地毯上的其他清洁位置移动的清洁操作期间用户所需的相对功的水平分量。功仅由移动设备在水平方向上测量的力来确定。 4.2 该测量与真空吸尘器的使用者所做的工作有关，可用于真空吸尘器之间的比较。 4.3 只有当真空吸尘器使用者按照制造商的说明正确操作真空吸尘器时，实际使用的真空吸尘器与操作方法之间的关系才有效。

1.1 This test method covers a measurement of the relative work required to move an upright, canister, stick, or combination vacuum cleaner in a straight line with forward and backward stroking on a selection of typical carpeted surfaces. 1.1.1 This test method measures only the horizontal component of work required to move the vacuum cleaner on carpet. 1.2 This test method can be used in the testing of household and commercial vacuum cleaners. 1.3 This test method measures the relative work needed to move the vacuum cleaner with its motor or motors in operation. 1.4 This test method applies to the vacuum cleaning of carpets only. 1.5 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. 1.6 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. Note 1: The F11.21 subcommittee is actively pursuing new market relevant carpets with the assistance of the carpet industry. Section 12 has been revised to remove carpets that are no longer available (that is, plush, Frieze). 1.7 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 measures the horizontal component of the relative work required by the user during the cleaning operation for the movement of a vacuum cleaner in the home or other cleaning location on standardized laboratory carpeting. Work is determined from the forces measured in the horizontal direction only by the mobility equipment. 4.2 This measurement is relative to the work performed by the user of vacuum cleaners and may be used for comparison between vacuum cleaners. 4.3 The relation between actual vacuum cleaner usage and the method of operation is valid only if the vacuum cleaner user operates the vacuum cleaner properly and in accordance with the manufacturer's instructions.
