ASTM E 2427 : 2018

1.1This test method is a performance test for acceptance of sieves.

1.2This test method compares the performance of a sieve against an inspection or calibration sieve using a known quantity of reference material such that the long-term stability of sieves can be measured.

1.3This is a test method for checking the accuracy and long-term reliability of test sieves. Since it is not possible to adjust the measuring capability of a test sieve, the test method is designed to offer a verification procedure based on sieving performance by comparison to a standard reference. This test method is not proposed as an alternative to the inspection methods in accordance with Specification E11 or the procedures in MNL 32.

1.4Units—The values stated in SI units are to be regarded as standard. The additional values given are included for information only and are not considered standard.

1.5This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
