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. SCOPE 1.1 This document specifies the technical requirements for; the woven wire test sieve cloth (sieve cloth) used in test sieves, the construction of test sieves, standard and non-standard test sieve frame sizes, and test procedures used to inspect sieve cloth and the test sieves. This specification applies to test sieves manufactured with sieve cloth having a nominal aperture size ranging from 125 millimetres (mm) down to 20 micrometres (μm). 1.2 Additional reference information can be found in Specifications E161, E323, E2016, and in Test Methods C430 and E2427. 1.3 The values stated in SI units shall be considered standard for the dimensions of the sieve cloth openings and the wire diameters used in the sieve cloth. The values stated in inch-pound units shall be considered standard with regard to the sieve frames, pans, and covers. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This 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.
Abstract
Overview
ASTM E11-22: Standard Specification for Woven Wire Test Sieve Cloth and Test Sieves establishes the technical requirements for woven wire sieve cloth and the construction of test sieves used for particle size analysis in a variety of industries. Developed and maintained by ASTM International, this standard applies to test sieves made using sieve cloth with nominal aperture sizes ranging from 125 millimetres (mm) down to 20 micrometres (μm). ASTM E11-22 is widely referenced for the reliable classification of materials by particle size using woven wire sieves, ensuring repeatable and consistent results in laboratory and industrial applications.
Key Topics
-
Sieve Cloth Requirements: Specifies material (stainless steel, brass, or bronze), weaving types (plain weave for ≥75 μm; twill weave permitted for ≤71 μm), dimensional tolerances, absence of coating, and defect criteria for sieve cloth used in test sieves.
-
Test Sieve Construction: Details standardized and non-standard frame sizes, allowed materials (typically brass or stainless steel for corrosion resistance), construction methods to maintain rigidity and avoid material catch points, and guidelines for attaching the sieve cloth.
-
Dimensional Tolerances and Measurement: Outlines permissible variations for average opening size, maximum opening, and wire diameter. Establishes the procedure for measuring sieve openings and wire diameters and defines quality levels (Compliance, Inspection, Calibration) based on confidence in measurement through truncated Gaussian distribution statistics.
-
Inspection and Certification:
- Compliance Sieves: Inspected before assembly; basic conformance.
- Inspection Sieves: Inspected after assembly with a required number of measured apertures; accompanied by a detailed certificate.
- Calibration Sieves: Most rigorous, with at least twice the number of apertures measured compared to inspection sieves; supplied with comprehensive certification.
-
Test Sieve Labeling: Specifies labeling requirements including reference to ASTM E11, manufacturer, sieve designation, and a unique serial number for traceability.
Applications
ASTM E11-22 is essential for industries involved in:
- Quality control laboratories conducting sieve analysis for particle size distribution
- Pharmaceutical manufacturing, where precise particle sizing impacts product quality
- Construction materials testing, such as determining aggregate gradation in concrete and asphalt
- Food and beverage industry analyzing powders and granular products
- Mining, metallurgy, and chemicals where raw material sizing is critical for processing
By providing clear requirements for the use, inspection, and documentation of woven wire test sieves, the standard ensures reliable, reproducible, and internationally recognized particle size analysis results. This enhances comparability across laboratories and compliance with regulatory or customer specifications.
