Abstract

Standard ASTM E11 was completely revised with the -09 revision, and further in subsequent years to apply tolerances in conformance with truncated Gaussian normal distribution statistics. It covers the requirements for the sieve cloth itself, and for the design and construction of test sieves that use sieve cloth as a particle sizing medium to classify materials. This specification incorporates a maximum standard deviation value (where applicable) for the sieve cloth and for the Test Sieves. The maximum standard deviation values in Table 1 have been corrected by a K factor so as to increase the confidence level of the sieve cloth and the Test Sieve. Three (3) different inspection confidence levels are applied for Compliance, Inspection and Calibration Test Sieves; with Calibration Test Sieves having at least twice as many openings measured as Inspection Sieves. Similar to previous ASTM E11 revisions the specification covers the Test Sieve and its construction; standard frame sizes, non-standard frames, dimensional information, characteristics of the sieve frame, materials of construction for the sieve frame, attachment of the sieve cloth to the sieve frame, and specifies how test sieves should be labeled. Lastly, the specification Annex discusses in detail the proper procedure for inspection of the sieve cloth and the test sieve, to ensure that it complies with the requirements as shown in Table 1 of the specification.
