Standard Specification for Wire Cloth and Sieves for Testing Purposes

SCOPE
1.1 This specification covers the requirements for design and construction of testing sieves using a medium of woven wire cloth mounted in a frame for use in testing for the classification of materials according to designated particle size (See Note 1 and Note 2), and wire cloth, meeting the specifications of , to be designated test grade wire cloth. All subsequent references to wire cloth shall mean test grade wire cloth. Methods for checking testing sieves and wire cloth for conformance to this specification are included in the annex.
Note 1--Complete instructions and procedures on the use and calibration of testing sieves are contained in ASTM STP447B. Note that sieve analysis results from two testing sieves of the same sieve designation may not be the same because of the variances in sieve opening permitted by this specification. To minimize the differences in sieve analysis results, the use of testing sieves matched on a performance basis is suggested. ASTM STP447B also contains a list of all published ASTM standards on sieve analysis procedures for specific materials or industries. This list may be referenced to obtain statements of precision and bias for sieve analysis of specific materials.
Note 2--For other types of sieves, see Specification E323 and Specification E161.
1.2 The values stated in SI units shall be considered standard for the dimensions of the wire cloth openings and the diameter of the wires used in the wire cloth. The values stated in inch-pound units shall be considered standard with regard to the sieve frames.
1.3 The following precautionary statement refers only to the test method portion, Annex A1, of this specification: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.

These standard designations correspond to the values for test sieve openings recommended by the International Standards Organization, Geneva, Switzerland, except
where noted.
D
These sieves are not in the standard series but they have been included because they are in common usage.
