1.1 本试验方法适用于家用中央真空清洁系统中使用的涡轮驱动喷嘴。 1.2 该试验方法提供了一种通过加速实验室程序确定涡轮机运行寿命（小时）的试验。涡轮机在动力喷嘴中安装和运行时进行测试。 1.3 该试验方法仅适用于涡轮驱动喷嘴。用于提供气流源的系统没有被考虑。 1.4 该试验方法仅限于确定家用涡轮机的涡轮机寿命- 动力喷嘴。 1.5 以英寸-磅为单位的数值应视为标准。括号中给出的值仅供参考。 1.6 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。 1.7 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 测试结果提供了涡轮机驱动喷嘴寿命的指示。涡轮机寿命的结束将根据 3.1.1 。

1.1 This test method covers the turbine-powered nozzle used in household central vacuum cleaning systems. 1.2 This test method provides a test for determining the operating turbine life in hours by an accelerated laboratory procedure. The turbine is tested while mounted and operated in the power nozzle. 1.3 This test method covers only the turbine-powered nozzle. The system used to provide the airflow source is not under consideration. 1.4 This test method is limited to the determination of turbine life for a household turbine-powered nozzle. 1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 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. 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 The test results provide an indication of the turbine-powered nozzle life. The end of turbine life will be judged in accordance with 3.1.1 .
