Full title and description

Test sieving — Part 1: Methods using test sieves of woven wire cloth and perforated metal plate (ISO 2591-1:1988). This International Standard describes factors affecting test sieving and specifies general principles for apparatus, procedure and presentation of results when using test sieves made from woven wire cloth or perforated metal plate.

Abstract

ISO 2591-1:1988 summarizes the main influences on sieving results (material properties, sieve characteristics, sample preparation and handling) and defines consistent approaches to apparatus condition, sieving procedures (hand and machine methods, dry and wet sieving), sample division and reporting of results. It applies to test sieving with woven wire cloth or perforated metal plate and provides guidance to obtain reproducible particle size distribution data.

Scope

This part of ISO 2591 specifies general principles to be followed when performing test sieving with test sieves made of woven wire cloth or perforated metal plate. It covers apparatus condition and maintenance, sample preparation and division, procedural choices (hand versus machine sieving, dry versus wet methods), and the presentation and reporting of results so that sieving outcomes are reproducible and comparable. ISO 2591-1:1988 cancels and partially replaces ISO 2591:1973. (Electroformed test sieve methods are addressed in ISO 2591-2.)

Key topics and requirements

• Principles of sieving: separation behaviour of much-smaller particles versus those close to aperture size and the importance of presenting particles to the apertures correctly.
• Material factors: effects of particle shape, density, moisture, friability, electrostatic and magnetic properties on sieving performance.
• Sampling and sample division: requirements for representative sampling, reduction to test charges and storage to avoid contamination or property changes.
• Apparatus and test sieve condition: requirements for using test sieves (woven wire cloth or perforated metal plate), inspection for defects, cleaning and limits on thermal treatment.
• Sieving methods: guidance on hand sieving and mechanical sieving, dry and wet procedures, nest combinations, charge sizing and avoiding overloading; recommendation for final hand sieving as a reference where machines are used.
• Calibration and verification: verification of effective aperture size and routine checks to ensure consistent performance.
• Reporting and presentation of results: mandatory declaration of method details (sieve type, machine or operator, sample preparation and conditioning) and how results are combined and expressed.

Typical use and users

Used by test laboratories, quality control and production teams, materials scientists and engineers who perform particle size analysis for aggregates, minerals, ceramics, powders, pigments, abrasives and similar bulk materials. Typical users include laboratory technicians, QC engineers, specification writers and procurement managers who require reproducible sieve-analysis methods for quality assurance, product specification and contractual testing.

Related standards

Related standards and documents frequently referenced with ISO 2591-1 include ISO 2591-2 (other test-sieve methods such as electroformed types), ISO 3310 (specifications for test sieves), standards on particle-size reporting such as ISO 9276 series, and national or sectoral test methods that reference ISO sieving practice. ISO 2591-1:1988 replaces parts of the earlier ISO 2591:1973.

FAQ

Q: What is this standard?

A: ISO 2591-1:1988 is an international standard that provides general principles and methods for test sieving using woven wire cloth or perforated metal plate test sieves, intended to produce reproducible particle-size distribution results.

Q: What does it cover?

A: It covers factors affecting sieving results (material and sieve properties), apparatus condition and maintenance, sampling and sample division, recommended sieving procedures (hand and machine, dry and wet), calibration/verification and the required form of reporting results.

Q: Who typically uses it?

A: Laboratory technicians, quality control and production engineers, materials scientists, standard writers and anyone performing or specifying sieve analysis for powders, aggregates, minerals, ceramics, pigments, abrasives and related materials.

Q: Is it current or superseded?

A: ISO 2591-1:1988 remains a published International Standard. It was reviewed and confirmed by ISO on 3 March 2023, and therefore that edition is current as confirmed on that date. Users should verify whether any newer revisions or national amendments apply for their specific use.
