Standard Specification for

Woven Wire Test Sieve Cloth and Test Sieves1
This standard is issued under the fixed designation E 11; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (´)indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.

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 inspectsieve cloth and the test sieves. This Specification applies to test sieves manufactured with sieve cloth having a nominal aperture size ranging from 125 millimeters (mm) down to 20 micrometers (µm). 1.2 Additional reference information can be found in Specifications E 161, E 323, E 2016, and in Test Methods C 430 and E 2427. 1.3 The values stated in SI units shall be considered standard for thedimensions 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 andhealth practices and determine the applicability of regulatory limitations prior to use. 2.

3. Terminology 3.1 Definitions: 3.1.1 aperture—the dimension defining an opening in a screeningsurface. 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 of crimp, which locks the wires in place, and in part establishes thefirmness 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 of firmness in sieve cloth is termed sleaziness. 3.1.4 matched test sieve—atest sieve that reproduces the performance results of another test sieve within user defined limits for a designated material (for information only and may not be in compliance with this Specification). 3.1.5 mesh—the number of wires or openings per linear inch (25.4 mm) counted from the center of any wire to a point exactly 1 in. (25.4 mm) distant, including the fractional distance between...
