Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONIndustrial wire cloth can be produced in many thousands of combinations of size and shape ofopening, wire diameter, type of weave, and

3、metal. This specification covers woven wire cloth forindustrial use, including the separation of particles. Its purpose is to introduce standard terms anddefinitions, to note the normal range of specifications woven, and to establish tolerances andrequirements. This specification excludes sieve clot

4、h from its scope, since this is covered underSpecification E11. If a user has a specific application for industrial wire cloth that is not within thescope of this specification, it is recommended that the wire cloth supplier be consulted.1. Scope1.1 This specification covers industrial woven wire fa

5、bric, referred to as wire cloth, for general use including the separation ofparticles. Wire cloth can be made of any primary metal or metal alloy wire that is suitable for weaving. This specification doesnot apply to the following special types of wire cloth: filter cloth or dutch weave (seeAppendix

6、 X1), fourdrinier and cylinder cloth,galvanized hardware cloth, insect wire screening, spiral weave wire cloth, testing sieve cloth, or welded wire cloth.1.2The values stated in inch-pound units shall be regarded as the standard. The values given in parentheses are for informationonly.1.2 The values

7、 stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions 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

8、 its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.1This specification is under the jurisdiction of ASTM Committee E29 on Particle and Spray Characterization and is

15、 sieving medium (see also width opening).3.1.23.2.3 bolting cloth, na specific group of commonly used mesh and wire diameter combinations. They are covered within thisspecification.3.1.3coatingswire cloth meeting a group of specifications that are typical for higher sifting capacities and which can

17、 become non-standard.3.2.4 firmness, nthe wire used for weaving wire cloth can be coated, plated, or in some other way finished prior to weaving,or wire cloth can be specified coated after weaving. Consult with a supplier as to the applicability of this specification. Examplesof possible coatings in

18、clude, but are not limited to, metallic plated, such as, copper, nickel, tin, and so forth, painted, orepoxy-coated or galvanized-steel wire cloth that has been coated with zinc either before or after weaving.3.1.4Types of Crimps:3.1.4.1crimp, nthe corrugation in the warp or shute wire, or both. The

19、 crimp in the wires is formed either during the weavingprocess, or with a crimping machine prior to weaving. If formed during the weaving process, the tension existing between the warpand shute wires fundamentally determines the respective amount or depth of crimp, which locks the wires in place and

20、 in partestablishes the firmness of the wire cloth.3.1.4.2double crimp, adjwire cloth woven with approximately equal corrugations in both the warp and shute wires to lock thewires in position (see Fig. 1).3.1.4.3flat top, adjwire cloth with deep crimps, as in lock crimp, except that all crimps are o

21、n the underside of the cloth,leaving the top surface all in one plane. Sometimes designated smooth top (see Fig. 2).3.1.4.4intermediate crimp, adjprecrimped wire cloth with extra crimps or corrugations between the points or intersection;sometimes designated intercrimp or multiple crimp. The warp, or

22、 shute wires, or both, may be intermediate crimped (see Fig. 3).3.1.4.5lock crimp, adjprecrimped wire cloth with deep crimps at points of intersection to lock the wires securely in place (seeFig. 4).3.1.4.6precrimp, adjwire cloth woven with both the warp and shute wires crimped before weaving.3.1.4.

23、7triple shute, adjwire cloth woven with three shute wires inserted adjacent to each other, often constructed inconformance with precrimp rectangular.3.1.5market gradea subjective term referring to the planar rigidity of wire cloth (as a roll good, not mounted in a frame).3.2.4.1 DiscussionFirmness i

24、s established by the tensile strength of the material, the relationship of the mesh to wirediameters, the type of weave, and amount of crimp in the wires. The absence of firmness in wire cloth is termed sleaziness.3.2.5 market grade wire cloth, na specific group of commonly used mesh and wire diamet

(25.4 mm) distant, including the fractional
