Filtration Standards

4.1 This guide addresses issues related solely to strategies and the development of a plan to address wildfire-related physical and chemical changes to water resources in Source Water Protection Areas. This guide does not include specific advice on risk assessment. Mitigation strategies and...

IEC TR 60522-2:2020 provides guidance on quality equivalent filtration and permanent filtration with regards to the requirements of IEC 60522-1 and its modifications versus IEC 60522:1999.

This document provides guidance on quality equivalent filtration and permanent filtration with regards to the requirements of IEC 60522-1 and its modifications versus IEC 60522:1999.

This document specifies product characteristics and test methods for strainer and filter components for water supply connections and pipe work in water mist systems. This document is applicable to strainers and filters with filtration grades up to 6 mm.

This SAE Aerospace Information Report (AIR) reviews performance testing parameters for fuel filter elements utilized in gas turbine engine and APU main fuel systems. The scope is limited to main fuel filter elements rated at 35 μm(c), or finer, which constitute the majority of contemporary engine...

1.1 This test method determines the bacterial retention characteristics of membrane filters for liquid filtration using Brevundimonas diminuta as the challenge organism. This test method can be used to evaluate any membrane filter system used for liquid sterilization. 1.2 This test method is...

5.1 This test method measures the concentration of cellular-ATP present in the sample. ATP is a constituent of all living cells, including bacteria and fungi. Consequently, the presence of cellular-ATP is an indicator of total metabolically active microbial contamination in fuels. ATP is not...

1.1 This test method covers an engine test procedure for evaluating diesel engine oils for performance characteristics, including viscosity increase and soot concentrations (loading).2 This test method is commonly referred to as the Mack T-8. 1.2 This test method also provides the procedure for...

The point-of-use (POU) and point-of-entry (POE) systems addressed by this Standard are designed to be used for the supplemental microbial control of specific organisms that may occasionally be present in drinking water (public or private) because of intermittent incursions. Certain of these...

5.1 Users of industrial woven wire filter cloth as covered by Specification E2814 commonly desire to specify the largest pore size as determined by converting the pressure result of a bubble point test to an absolute filtration rating in micrometres (also known as microns). This test method...

1.1 This test method covers an engine test procedure for the measurement of the effects of automotive engine oils on the fuel economy of passenger cars and light-duty trucks with gross vehicle weight 3856 kg or less. The tests are conducted using a specified spark-ignition engine with a...

This document specifies particle filters for use as replaceable components in unassisted respiratory protective devices (RPD) with the exception of escape devices and filtering face pieces. Laboratory tests are included for the assessment of compliance with the requirements. Some filters complying...

1.1 This practice applies to the classification, design, manufacture, construction, operation, maintenance, and inspection of stationary waves. 1.2 Stationary wave systems shall be defined as a system that delivers a constantly flowing sheet of water nominally up to 24 in. thick travelling over a...

5.1 This test method is intended for use in evaluating the cleanliness of middle distillate fuels for quality control purposes. 5.2 The filter media specified in this procedure is suitable for the materials in the scope. 5.3 A change in filtration performance after storage or pretreatment...

This test method determines the bacterial retention characteristics of membrane filters for liquid filtration using Brevundimonas diminuta as the challenge organism. This test method can be used to evaluate any membrane filter system used for liquid sterilization. This test method is not...

This test method covers a protocol for capturing, extracting and quantifying the cellular adenosine triphosphate (cellular-ATP) content associated with microorganisms found in fuels and fuel-associated water. The ATP is measured using a bioluminescence enzyme assay, whereby light is generated in...

This specification is primarily intended to help ensure barrier face coverings meeting the stated requirements provide (1) a means of source control for individual wearers by reducing the number of expelled droplets and aerosols from the wearer's nose and mouth into the air; and (2) to potentially...

1.1 This specification is primarily intended to help ensure barrier face coverings meeting the stated requirements provide (1) a means of source control for individual wearers by reducing the number of expelled droplets and aerosols from the wearer's nose and mouth into the air; and (2) to...

This test standard shall be used to determine the hydraulic characteristics of stormwater filtration elements. Elements tested shall be of a size commonly manufactured, not a scale model. The position and orientation of all filter elements during testing shall be identical to the position...
