ASTM E1638-22 PDF

Overview

ASTM E1638-22 – Standard Terminology Relating to Sieves, Sieving Methods, and Screening Media – provides a comprehensive set of defined terms and concepts fundamental to particle size analysis, sieving, and screening processes. Developed under the jurisdiction of ASTM Committee E29 on Particle and Spray Characterization, this terminology standard is essential for professionals involved in the manufacture and use of standard test sieves, screening media, and related particle characterization methods.

By harmonizing precise definitions, ASTM E1638-22 fosters accurate communication, data comparison, and best practices throughout laboratory, industrial, and research settings where particle size determination and particle separation are critical.

Key Topics

This terminology standard covers a range of essential concepts and definitions relevant to:

• Sieves and Sieve Cloth: Definitions of test sieves (including electroformed, wire cloth, and perforated plate sieves), mesh size, sieve aperture, and sieve cloth construction.
• Screening Media: Terms related to woven wire cloth, filter cloth (including Dutch weave and market grade), crimp types, and perforated plate patterns.
• Sieving and Screening Methods: Descriptions of sieving processes, screening procedures, use of sieve shakers, cumulative distribution graphs, and particle size analysis.
• Particle Size and Measurement: Terms such as particle size distribution, micron rating, median particle size, percent retained and passing, bulk density, porosity, and absolute filtration rating.
• Certifications and Traceability: Definitions concerning material certification, certificates of compliance, heat and lot numbers, inspection reports, and revision levels to ensure product quality and traceability.
• Units and Conventions: Standardization of inch-pound as the primary unit, with SI units provided for reference.

This standard excludes terms in common usage that appear in general-language dictionaries, focusing only on specialized and industry-specific vocabulary necessary for technical consistency.

Applications

ASTM E1638-22 terminology is crucial for a diverse range of industries and applications where particle sizing, material screening, and separation processes are integral, including:

• Materials Testing Laboratories: Ensures uniform understanding of test procedures and results for soil, aggregates, powders, and other materials.
• Manufacturing and Quality Control: Supports specification and quality management for sieves, screening equipment, and raw materials in sectors such as mining, pharmaceuticals, food processing, and chemicals.
• Filter and Screen Production: Promotes consistent manufacturing, certification, and sourcing of woven wire cloth, filter cloth, perforated plates, and custom screening media.
• Compliance and Documentation: Assists in fulfilling regulatory requirements for reporting, documentation, and international trade, including traceability and certification of sieve and screen components.

By standardizing terminology, ASTM E1638-22 enhances the reliability of data exchange, method interpretation, and global communication across organizations and supply chains wherever sieving, screening, or filtration is involved.
