Standard Methods for Gas Flow Resistance Testing of Filtration Media
 N F778

Annotation

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

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.

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

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

Стандартные методы для тестирования сопротивления потока газа СМИ фильтрации

Сопротивление потока любого произведенного устройства фильтра будет зависеть от сопротивления потока используемых СМИ.

Этот стандарт предлагает процедуры, достаточные для определения особенностей потока газа плоских экземпляров СМИ, используемых в процессе фильтрации. Методы расширены для включения плиссируемых экземпляров и оптовых СМИ также.
