ISO 2395:1990

Overview

ISO 2395:1990 - Test sieves and test sieving - Vocabulary is an international, bilingual (English/French) vocabulary that standardizes terminology related to test sieves and test sieving. This second edition (1990) replaces the 1972 edition and is intended to ensure consistent use of terms across laboratories, industry and regulatory documents. It applies to test sieves manufactured and used in accordance with related standards (see Related Standards).

Key topics and technical scope

The standard provides precise definitions and terms organized around major topics:

• Material to be sieved
  • particle, agglomerate, sample, test sample (prise d’essai), charge, apparent bulk density, particle density
• Test sieves and components
  • sieve / test sieve, certified test sieve, matched test sieve, full set, nest of sieves
  • sieve parts: frame, sieving medium, lid (cover), receiver (pan)
  • geometric features: aperture size, pitch, wire diameter, bridge width, margin, sieve depth/height, plate thickness
  • sieving media types: woven wire cloth, perforated plate, electroformed sheet; weave types (plain, twilled); percentage open area
• Test sieving processes
  • sieving, test sieving, particle size analysis by sieving, hand sieving, machine sieving
• Expression of results and indexing
  • terminology for reporting sieving outcomes, alphabetical indexes in English and French

The vocabulary clarifies phraseology used in test-sieve manufacture, calibration, testing procedures and reporting - helping avoid ambiguity in specifications and test reports.

Applications and who uses it

ISO 2395 is valuable to anyone involved in particle size analysis, sieving equipment or quality control:

• Testing laboratories performing particle size analysis by sieving
• Quality control and R&D in industries such as mining, aggregates, cement, ceramics, pharmaceuticals, food and chemicals
• Manufacturers and calibrators of test sieves and sieving equipment
• Standards bodies and regulators that reference consistent terminology in test methods and certifications
• Procurement and specification writers who need precise term usage in contracts and technical documents

Using ISO 2395 helps ensure consistent communication between suppliers, labs and regulators when specifying sieve types, interpreting test results, and maintaining traceability.
