Overview

ISO 4783-2:1989 - "Industrial wire screens and woven wire cloth - Guide to the choice of aperture size and wire diameter combinations - Part 2: Preferred combinations for woven wire cloth" provides a standardized, tabulated set of preferred aperture size and wire diameter combinations for industrial woven wire cloth. The part applies to aperture widths from 16 mm down to 0.02 mm and is intended as a practical guide to selecting combinations that balance open area, strength and mass for woven wire cloth used in industrial screening and filtration.

Key topics and requirements

Scope: Preferred combinations for woven wire cloth derived from the general list in ISO 4783‑1. Applies to aperture sizes 16 mm → 0.02 mm.

Designation: Woven wire cloth shall be designated in sequence by: a) width of aperture (w), b) diameter of wire (d), c) material of wire, d) type of weave.

Tabulated data (Table 1): Lists preferred w/d combinations and gives open area (A) and mass per unit area for each combination. Table covers a wide range of wire diameters and aperture widths for plain and twilled weaves.

Mass calculation (Table 2 & formula): Mass per unit area (kg/m2) is provided and can be calculated using the formula: mass = (d^2 × ρ) / [618.1 × (w + d)] where d = wire diameter (mm), w = aperture width (mm), and ρ = material density (kg/m3). Table 2 lists typical material densities (e.g., plain/carbon steel 7850 kg/m3, stainless steel ~7900 kg/m3, aluminium ~2700 kg/m3, copper ~8900 kg/m3).

Weave types: Includes plain and twilled weave designations and notes on open area differences.

Applications and users

ISO 4783-2 is practical for anyone specifying, manufacturing, procuring or testing woven wire cloth for industrial sieving and screening applications, including:

Screen and sieve manufacturers

Process and mechanical engineers (mining, aggregates, chemical, filtration)

Purchasing and quality assurance teams specifying screen products

Test laboratories and inspection bodies

Designers of separation, filtration and screening equipment

Using ISO 4783-2 helps standardize product descriptions, ensures interchangeability, and simplifies selection of aperture/wire combinations to meet required open area and structural mass criteria.
