ASTM E2814-22

Standard Specification for Industrial Woven Wire Filter Cloth

ABSTRACT
This specification covers the special grade of industrial woven wire cloth, referred to as filter cloth (also known as, Dutch weave or Hollander weave), for general filtration including the separation of solids from fluids (liquids or gases), based on a desired particle size retention. Filter cloth can be made of any primary metal or metal alloy wire that is suitable for weaving, and is woven with a greater number of wires in one direction than the other, and utilizing two different wire diameters. E2814 introduces standard terms and definitions, observes common technical considerations that a user should be aware of, and presents alternative acceptance criteria based on a desired pore size, or micron retention filtration rating.
SCOPE
1.1 This specification covers the special grade of industrial woven wire cloth, referred to as filter cloth, for general filtration including the separation of solids from fluids (liquids or gases), based on a desired particle size retention. Filter cloth can be made of any primary metal or metal alloy wire that is suitable for weaving.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, 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.  
1.4 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.

INTRODUCTION
Industrial metal filter cloth is a special type of woven wire cloth that can be produced in many
specifications,oftenproprietaryinnature.SometimesreferredtoasDutchweaveorHollanderweave,
filter cloth can be woven in a variety of metals and is woven with a greater number of wires in one
direction than the other, and utilizing two different wire diameters. This specification covers woven
wire filter cloth for industrial use, which is commonly rated by its micron retention capability. Its
purpose is to introduce standard terms and definitions, to observe common technical considerations
that a user should be aware of, and to present alternative acceptance criteria based on a desired pore
size, or micron retention filtration rating. It should be noted this specification excludes standard
industrial woven wire cloth and sieve cloth from its scope, since these are covered under
Specifications E2016 and E11, respectively, as well as excludes plastic and synthetic filter cloth.
