ASTM E323-80(2004)

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 .

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.

For other types of sieves see ASTM Specification E 11 and ASTM Specification E 161, for Precision Electroformed Sieves.

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.

1.2 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.
