1.1 本试验方法为测量真空过程直接产生的颗粒提供了实验室试验。 1.2 本试验方法适用于所有住宅/商业支柱、罐、stickvacs、中央真空系统和组合清洁器。 1.3 本试验方法适用于测试地板覆盖物的除尘，而不是表面垃圾和碎屑的清除。 1.4 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 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）。本标准的用户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（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 在本试验方法中，将测定通过在被灰尘污染的特定地板上操作真空吸尘器而产生的空气颗粒量。将测量电机、地板覆盖物和测试灰尘中的颗粒。由于地板覆盖物、土壤和其他固体颗粒成分、单个操作员使用的吸尘过程、供暖、通风和空调（HVAC）系统的空气交换率以及其他因素的变化，实验室实践中产生的粉尘量将不同于住宅/商业设施中的粉尘量。 4.2 为衡量 4.1 本试验方法中使用了标准试验箱、设备、地板覆盖材料和粉尘颗粒。 4.3 由于目前在真空吸尘器行业的产品中观察到大量生成的颗粒数，因此根据该测试方法生成的最大颗粒数的测试结果以对数表示 10 产品性能评估和比较的等价物。

1.1 This test method provides a laboratory test for the measurement of particulate generated as a direct result of the vacuuming process. 1.2 This test method is applicable to all residential/commercial uprights, canisters, stickvacs, central vacuum systems, and combination cleaners. 1.3 This test method applies to test dust removal from floor coverings not the removal of surface litter and debris. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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 In this test method, the amount of particulate generated into the air by operating a vacuum cleaner over a specific floor covering that is contaminated with dust will be determined. Particles from the motor, floor covering, and the test dust will all be measured. The amount of dust generated in the laboratory practice will differ from that in residential/commercial installations because of variations in floor coverings, soil and other solid particulate compositions, the vacuuming process used by individual operators, the air exchange rate of heating, ventilation, and air conditioning (HVAC) systems, and other factors. 4.2 To provide a uniform basis for measuring the performance in 4.1 , a standardized test chamber, equipment, floor covering material, and dust particulate are used in this test method. 4.3 Due to the large range of generated particle counts observed among products in the vacuum cleaner industry at the present time, the test results of the maximum particle counts generated under this test method are expressed in Log 10 equivalents for evaluation and comparison of product performance.
