1. Scope
1.1 This document specifies the technical requirements for;
the woven wire test sieve cloth (sieve cloth) used in test sieves,
the construction of test sieves,standard and non-standard test
sieve frame sizes, and test procedures used to inspect sieve
cloth and the test sieves. This Specification applies to test
sieves manufactured with sieve cloth having a nominal aperture size ranging from 125 millimetres (mm) down to 20
micrometres (µm).
1.2 Additional reference information can be found in Specifications E161, E323, E2016, and in Test Methods C430 andE2427.
1.3 The values stated in SI units shall be considered
standard for the dimensions of the sieve cloth openings and the
wire diameters used in the sieve cloth. The values stated in
inch-pound units shall be considered standard with regard to
the sieve frames, pans, and covers.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Definitions:
3.1.1aperture—the dimension defining an opening in a
screening surface.
3.1.2 crimp—the corrugation in the warp and shute wire, or
both. The crimp in the wires is formed either during the
weaving process, or with a crimping machine prior to weaving.
If formed during the weaving process, the tension existing
between the warp and shute wires fundamentally determines
the respective amount or depth ofcrimp, which locks the wires
in place, and in part establishes the firmness of the sieve cloth.
3.1.3 firmness—a subjective term referring to the planar
rigidity of sieve cloth (as a roll good, not mounted in a test
sieve frame), established by the tensile strength of the material,
the relationship of the mesh to wire diameters, the type of
weave, and amount of crimp in the wires. The absence...
