ASTM Standards for Filters: Which Ones Vens Filters Meet

Filter specifications from refineries, power plants, airports and pharmaceutical plants often name ASTM test methods. Vens Hydroluft filters can meet the ASTM standards below, depending on the product. This page lists each standard, what it measures and which Vens filters it applies to, with a link to a fuller article on each.

The standards

Standard	What it measures	Vens filters it applies to
ASTM F316	Bubble point and pore size of membrane filters	Membrane cartridges: PES, nylon 66, PTFE and PFA
ASTM F838	Bacterial retention of membrane filters for liquids	Sterilising-grade membrane cartridges
ASTM D7647	Particle counts in hydraulic and lubricating oils	Hydraulic and lube oil filter elements
ASTM D6786	Particle counts in mineral insulating (transformer) oil	Elements for transformer oil filtration
ASTM D7619	Particle counts in diesel and other distillate fuels	Fuel filter elements and cartridges
ASTM D3948 and D7224	Water separation rating of jet fuel	Fuel coalescer and separator elements
ASTM D2276 and D5452	Particulate contamination in aviation fuel, by mass	Aviation fuel filter elements

Articles on each:

• ASTM F316: bubble point and pore size of membrane filter cartridges

• ASTM F838: bacterial retention test for sterilising-grade membrane filters

• ASTM D7647: particle counting of hydraulic and lubricating oils

• ASTM D6786: particle count in transformer insulating oil

• ASTM D7619: particle counting in diesel and distillate fuels

• ASTM D3948 and D7224: water separation of jet fuel and coalescers

• ASTM D2276 and D5452: particulate contamination in aviation fuel

What "meets the standard" means

Most of these standards are test methods. A test method sets out how to measure something: pore size, bacteria passed, particles per millilitre, milligrams of dirt per litre. It does not set the pass mark. The pass mark comes from a specification: yours, the fuel or oil specification, or the equipment maker's.

So a filter meets one of these standards when, tested by that method, it gives the result the specification asks for. A membrane cartridge meets an F316 requirement when its bubble point is at or above the figure specified. A hydraulic element meets a D7647 requirement when the oil it cleans reaches the cleanliness code specified. Which Vens filter meets which requirement depends on the product and its rating, so tell us the standard and the figure your specification names, and we will confirm the element.
