1、Designation: E 11 09Standard Specification forWoven Wire Test Sieve Cloth and Test Sieves1This standard is issued under the fixed designation E 11; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A number
2、 in parentheses indicates the year of last reapproval. A superscriptepsilon () 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. Scope1.1 This document specifies the technical requirements for;the w
3、oven wire test sieve cloth (sieve cloth) used in test sieves,the construction of test sieves, standard and non-standard testsieve frame sizes, and test procedures used to inspect sievecloth and the test sieves. This Specification applies to testsieves manufactured with sieve cloth having a nominal a
4、per-ture size ranging from 125 millimeters (mm) down to 20micrometers (m).1.2 Additional reference information can be found in Speci-fications E 161, E 323, E 2016, and in Test Methods C 430 andE 2427.1.3 The values stated in SI units shall be consideredstandard for the dimensions of the sieve cloth
5、 openings and thewire diameters used in the sieve cloth. The values stated ininch-pound units shall be considered standard with regard tothe sieve frames, pans, and covers.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibilit
6、y of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

The crimp in the wires is formed either during theweaving process, or with a crimping machine prior to weaving.If formed during the weaving process, the tension existing
10、between the warp and shute wires fundamentally determinesthe respective amount or depth of crimp, which locks the wiresin place, and in part establishes the firmness of the sieve cloth.3.1.3 firmnessa subjective term referring to the planarrigidity of sieve cloth (as a roll good, not mounted in a te
11、stsieve frame), established by the tensile strength of the material,the relationship of the mesh to wire diameters, the type ofweave, and amount of crimp in the wires. The absence offirmness in sieve cloth is termed sleaziness.3.1.4 matched test sievea test sieve that reproduces theperformance resul

Sieve Cloth Requirements5.1 The sieve cloth used in test sieves shall meet therequirement
26、s of Table 1 and shall be designated SpecificationE 11 Sieve Cloth. The number of inspected apertures shall bein accordance with Table 1 (Column 7). Sieve cloth conform-ing to this specification shall be woven from stainless steel,brass, or bronze. Sieve cloth with openings greater than orequal to 7
27、5 micrometers shall be woven using a plain weave.For sieve cloth with openings equal to or less than 63micrometers the sieve cloth may be supplied using a twillweave. The sieve cloth shall not be coated or plated.5.2 All measurements of openings and wire diameters shallbe made along the midpoints of
28、 the openings as shown in Fig.1.5.3 There shall be no punctures or obvious defects in thesieve cloth.5.4 Test sieves can be supplied based on different levels ofconfidence as Compliance Sieves, Inspection Sieves, andCalibration Sieves. Calibration sieves have had at least twice asmany openings measu
29、red as Inspection sieves.5.5 Each test sieve must be examined and found to be freeof manufacturing defects.6. Technical Requirements6.1 Opening Sizes, Tolerances, and Standard Deviation:6.1.1 Four tolerances shall be applied: the variation foraverage opening (Y), the maximum variation (X), the maxim
30、umstandard deviation and the wire diameter. The opening toler-ances apply to the opening sizes, measured on the midpoint ofthe opening (see Fig. 1), and applied separately in both thewarp and shute directions.6.1.2 The average opening size shall not exceed the sievedesignation by more than 6Y (Table
31、 1, Column 4):Y 5w0.98271 1.6 (1)where Y and w are expressed in micrometers.6.1.3 The maximum opening size measured shall not exceedthe nominal opening size w (Table 1, Column 1), by more thanX (Table 1, Column 5):X 52w0.75!31 4w0.25(2)where X and w are expressed in micrometers.6.1.4 The intermediat
32、e value Z shall be stated as follows:Z 5 X 1 Y! / 2 (3)6.1.5 The maximum standard deviation is calculated basedon the Gaussian normal distribution curve, where the areaunder the curve to the maximum value X minus the area underthe curve to the intermediate value Z, is equal to this criticalarea betw
33、een (w + Z) and (w + X) not exceeding more than 5 %of the openings (see Appendix X2). The resulting tolerancesfor sigma are given in Table 1 for Compliance sieve cloth(Column 8).6.1.5.1 In order to increase the probability or acceptanceconfidence level from 66 % at one-sigma to Xs, specifically99 %
