Abstract

ASTM Standard E11 covers the requirements for sieve cloth, as well as for the design and construction of test sieves, that are used to classify materials by particle size. Sieving is commonly employed in both laboratory and production environments for particle analysis and size distribution.Standard E11 specifies 3 different tolerances for the sieve cloth openings; the average, the maximum, and the maximum standard deviation of the openings. Further, 3 different sampling confidence levels are applied for Compliance, Inspection and Calibration test sieves; with Calibration sieves having at least twice as many openings measured as Inspection sieves.The Specification Annex discusses in detail the proper procedure for the inspection of the sieve cloth and the test sieve, to ensure that it complies with the requirements of the specification.A recent analysis per revision E11-24 indicated over 95% of the opening inspection data sets exhibited distribution normality, which confirmed the use of Gaussian normal distribution statistical techniques are valid and appropriate for the maximum standard deviation tolerances.
