Standard Specification for Perforated-Plate Sieves for Testing Purposes

SCOPE
1.1 This specification covers perforated plate with either round or square apertures, normally mounted in a frame for use as sieves in precision testing in the classification of materials according to designated nominal particle size. A method for checking the accuracy of perforated sieve plates is included as information in Appendix X1.
Note 1--The perforated-plate sieves covered by this specification are intended for general precision testing. Some industries may require more restricted specifications for sieves for special testing purposes.
Note 2--For other types of sieves see ASTM Specification E11 and ASTM Specification E161, for Precision Electroformed Sieves.
Note 3--Complete instructions and procedures on the use of test sieves are contained in ASTM STP 447, Manual on Test Sieving Methods. This manual also contains a list of all ASTM published standards on sieve analysis procedures for specific materials or industries.
