【国外标准】 Standard Test Method for Characterizing the Pressure Drop and Filtration Performance of Cleanable Filter Media

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.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.
