Overview

ISO 9045:1990 - "Industrial screens and screening - Vocabulary" is an ISO vocabulary standard prepared by ISO/TC 24. Rather than specifying test methods or performance criteria, it provides a concise set of standardized terms and definitions frequently used in industrial screening practice. The vocabulary links test sieves and laboratory sieving terminology with industrial screening concepts and references related technical standards (ISO 4783‑1, ISO 4783‑2, ISO 4783‑3 and ISO 9044). For laboratory sieving terms, it refers to ISO 2395.

Key topics and definitions

ISO 9045 groups definitions into four sections and defines foundational terms used across screening activities:

• Material to be screened

  • particle (deprecated: grain), particle size (sieve size), agglomerate, fines
  • moisture: inherent (contained) moisture, surface moisture, bone‑dry
  • bulk density, relative density (deprecated: specific gravity), percentage of solids, angle of repose, feed

• Industrial screens and screening surfaces

  • screen / screening surface / screen deck
  • woven wire cloth (wire screen), perforated plate
  • aperture size, mesh count, wire diameter, percentage open area
  • square and slotted (rectangular) mesh, round‑hole equivalent, bridge width, pitch, margin
  • construction terms: warp, weft, crimp, plain/twilled weave, punch side, plate thickness

• Screen types and processes

  • named equipment and motions such as sifter (rotary screening motion) and grizzly (robust coarse screening)

• Products of screening

  • terminology for screened fractions and process outputs (fines, oversize, etc.)

These definitions are intentionally selective to introduce industrial screening and to harmonize terms used across overlapping ISO standards.

Practical applications and users

ISO 9045 is useful wherever consistent terminology improves clarity and reduces ambiguity in industrial screening activities:

• Equipment manufacturers and designers - for clear product specifications and drawings
• Process and mechanical engineers - to specify screening systems, feeds and acceptance criteria
• Quality assurance and testing laboratories - to harmonize report language with industrial practice
• Procurement and contracts - to avoid misinterpretation of terms in supply agreements
• Training, technical documentation and translation - for consistent multilingual terminology
• Standards committees and regulatory bodies - as a reference vocabulary when drafting related standards

Related standards

• ISO 4783‑1:1989, ISO 4783‑2:1989, ISO 4783‑3:1981 - guidance on aperture size and wire diameter combinations for wire screens
• ISO 9044:1990 - industrial woven wire cloth - technical requirements and testing
• ISO 2395:1972 - test sieves and test sieving - vocabulary (laboratory sieving terms)

Using ISO 9045:1990 as a common vocabulary helps reduce miscommunication across procurement, design, testing and operation of industrial screening systems.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 technical committees. Each member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for voting. Publication as an International Standard requires
approval by at least 75 % of the member bodies casting a vote.

Introduction
lSO/TC 24 has prepared several International Standards covering test sieves, test
sieving and industrial screens. Since these subjects are connected and the standards
overlap, a vocabulary is needed to define terms which are used in the different con-
texts. Such a vocabulary could be unwieldy, however, since numerous terms are used
in industrial screening practice, many of them for a particular material, type of screen
or screening process. Accordingly, this International Standard has been compiled to
cover the association of test sieves and test sieving with industrial screening, and to
include only a selection of other terms which suffice to introduce industrial screening
and screens.
Terms connected particularly with the test sieving process which is used in laboratory
particle size analysis are defined in IS0 2395: 1972, Test sieves and test sieving -
Vocabulary.

Introduction
ISO/TC 24 a elabore plusieurs Normes internationales sur les tamis de controle, le
tamisage de controle et les tissus industriels. Comme ces sujets sont connexes et que
les normes se chevauchent, il est necessaire d’avoir un vocabulaire definissant Des ter-
mes utilises dans differents contextes. Toutefois, un vocabulaire peut etre surcharge
du fait que de nombreux termes sont utilises dans la pratique du criblage industriel
dont une grande partie se rapporte a un materiau particulier, a un crible don& ou a un
procede de criblage. C’est pourquoi la presente Norme internationale a ete redigee de
maniere a associer les tamis de controle et le tamisage de controle au criblage indus-
triel, et a inclure uniquement une selection d’autres termes, suffisants pour introduire
la notion du criblage et des cribles.
Les termes relatifs au tamisage de controle utilise pour I’analyse granulometrique dans
Ies laboratoires sont definis dans I’ISO 2395: 1972, Tamis et tamisage de contHe -

Introduction
ISO/TC 24 a elabore plusieurs Normes internationales sur les tamis de controle, le
tamisage de controle et les tissus industriels. Comme ces sujets sont connexes et que
les normes se chevauchent, il est necessaire d’avoir un vocabulaire definissant Des ter-
mes utilises dans differents contextes. Toutefois, un vocabulaire peut etre surcharge
du fait que de nombreux termes sont utilises dans la pratique du criblage industriel
dont une grande partie se rapporte a un materiau particulier, a un crible don& ou a un
procede de criblage. C’est pourquoi la presente Norme internationale a ete redigee de
maniere a associer les tamis de controle et le tamisage de controle au criblage indus-
triel, et a inclure uniquement une selection d’autres termes, suffisants pour introduire
la notion du criblage et des cribles.
Les termes relatifs au tamisage de controle utilise pour I’analyse granulometrique dans
Ies laboratoires sont definis dans I’ISO 2395: 1972, Tamis et tamisage de contHe -
VocabuIaire.
