DIN ISO 11057:2012-05

This International Standard presents a test method for the comparative characterization of pulse-jet cleanable filter media, to be used in filter elements (e. g. bag filters, pocket filters, cartridge filters) applied in dry gas cleaning under standardized test conditions. Cleanable filters are usually employed in the raw gas in the range of some hundred mg/m3 up to some hundred g/m3. The systematic characterization and evaluation of filter media with respect to their relevant long-time operational properties (filtration- and cleaning-behaviour) and emission in addition to their well defined textile properties is still not only a major problem for the developers and manufacturers of filter-media, but also for the producers and users of filter installations. The test procedure, the characteristics of the required test facility, the test conditions and the evaluation and presentation of the results are specified. Examples of test results are demonstrated in a sample test report. Additional tasks such as verifying filter media concerning PM2,5 emissions, the classification of different media according to their filtration performance or the cleanability and durability of filter elements (i.e. projection of bag life-time) are addressed.
