1.1 本试验方法描述了可清洗过滤介质在规定实验室条件下的操作性能。 1.2 本试验方法确定了脉冲清洗过滤介质的气流阻力、阻力、清洗要求和微粒过滤性能。 1.3 该试验方法确定了可清洗过滤介质的相对性能。 1.4 该试验方法的结果对过滤介质的设计、施工和选择有帮助。 1.5 通过本试验方法获得的结果不应用于预测全尺寸织物过滤器（袋式除尘器）设施的绝对性能，但这些结果将有助于选择合适的过滤介质，并确定这些全尺寸织布过滤器设施的推荐操作参数。 1.6 以国际单位表示的数值视为标准值。括号中给出的值是以英寸为单位的数学转换- 英镑单位，仅供参考，不被视为标准单位。 1.7 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。 1.8 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====== 5.1 本试验方法确定了过滤介质的比较性能。研究结果可用于过滤介质的设计、制造、施工和选择。 5.2 通过本试验方法获得的结果不应用于预测全尺寸织物过滤器（袋式除尘器）设施的绝对性能，但这些结果将有助于选择合适的过滤介质，并确定这些全尺寸织布过滤器设施的推荐操作参数。 5.3 粉尘类型差异很大；因此，使用标准粉尘获得的结果不应外推到其他粉尘类型。

1.1 This test method characterizes the operational performance of cleanable filter media under specified laboratory conditions. 1.2 This test method determines the airflow resistance, drag, cleaning requirements, and particulate filtration performance of pulse cleaned filter media. 1.3 This test method determines the comparative performance of cleanable filter media. 1.4 The results obtained from this test method are useful in the design, construction, and selection of filter media. 1.5 The results obtained by this test method should not be used to predict absolute performance of full scale fabric filter (baghouse) facilities, however these results will be useful in selection of proper filter media and identification of recommended operating parameters for these full scale fabric filter facilities. 1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.7 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. 1.8 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 ====== 5.1 This test method determines the comparative performance of filter media. The results can be used for design, manufacturing, construction and selection of filter media. 5.2 Results obtained by this test method should not be used to predict absolute performance on full scale fabric filter (baghouse) facilities, however these results will be useful in selection of proper filter media and identification of recommended operating parameters for these full scale fabric filter facilities. 5.3 Dust types vary greatly; therefore, the results obtained using the standard dust should not be extrapolated to other dust types.
