ASTM F778-88(2023) PDF

Scope: 1.1 The flow resistance of any fabricated filter device will depend on the flow resistance of the media used. 1.2 This standard offers procedures sufficient to determine the gas flow characteristics of flat specimens of media used in the filtration process. The methods are extended to include pleated specimens and bulk media as well. 1.3 In all cases, flow rates through the specimen are determined in accordance with procedures outlined in ASME “Fluid Meters.” The test fluid is air. 1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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. 1.5 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.
