ASTM-E161 › Standard Specification for Electroformed Material and Test Sieves
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This specification covers the requirements for design and construction of electroformed sieves. These sieves are used to perform particle-size distribution analysis and in preparing narrowly designated particle-size fractions. They may also be used as reference standards when suitably calibrated. A method of calibrating these sieves is included in the Annex.
Note 1--Complete instructions and procedures on the use and calibration of testing sieves are contained in ASTM Manual 32. This publication also contains a list of all published ASTM Standards on sieve analysis procedures for specific materials or industries.
1.2 The 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.
Note 2--For other types of sieves, see Specifications E11 and E323.
1.3 The values stated in SI units shall be considered standard for the dimensions of the electroformed mesh openings and the size of the wires in the electroformed mesh. The values stated in inch units shall be considered standard with regard to the sieve frames.
