CONTAINED IN VOL. 11.03, 2017 Provides procedures sufficient to determine the gas flow characteristics of flat specimens of media used in the filtration process.

1.1The flow resistance of any fabricated filter device will depend on the flow resistance of the media used.

1.2This 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.

1.3In all cases, flow rates through the specimen are determined in accordance with procedures outlined in ASME “Fluid Meters.” The test fluid is air.

1.4This 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 and health practices and determine the applicability of regulatory limitations prior to use.
