1.1 本试验方法涵盖家用或商用单电机和双电机立式真空吸尘器（具有独立电机的立式吸尘器，用于产生真空和驱动地刷）的电机寿命评估。自行式或动力辅助清洁器不在本试验方法的范围内。 1.2 本试验方法仅限于立式真空吸尘器电机的评估。 1.3 该测试方法提供了一种测试，在需要维修之前，通过加速实验室程序确定电机的使用寿命。电机在立式真空吸尘器中安装和操作时进行测试。 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 本标准并非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 测试结果提供了电动立式真空吸尘器电机寿命的指示。 电机寿命结束将根据第节进行判断 3. 。

1.1 This test method covers motor life evaluation of household or commercial single and dual motor upright vacuum cleaners (uprights with separate motors for creating the vacuum and driving the floor brush). Self-propelled or power-assist cleaners are not within the scope of this test method. 1.2 This test method is limited to evaluation of the upright vacuum cleaner electric motor(s). 1.3 This test method provides a test to determine operating life of the motor(s), before servicing is needed, by an accelerated laboratory procedure. Motor(s) are tested while mounted and operated in the upright vacuum cleaner. 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, which 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 The test results provide an indication of the motor life of an electric upright vacuum cleaner. End of motor life will be judged in accordance with Section 3 .
