Industry convention covers the requirements for knitted wire mesh. Reproduced below: the complete specification table, the tolerance classes, and the companion and equivalent standards referenced when ordering to this document.
Industry convention — Scope
Industry convention specifies the designation system, dimensions and tolerances of knitted wire mesh — mesh count or nominal opening, wire diameter and the permissible aperture deviations. Alloy chemistry, mechanical testing and delivery condition are governed by separate documents in the same standards family.
Tolerance Classes
Industry convention defines tolerance limits on the average aperture and on the maximum single aperture, tightening as the aperture gets finer. For test-sieve duty the tighter ISO 3310-1 tolerances apply instead of the general cloth tolerances — specify sieve grade explicitly if the mesh will be used for particle-size analysis.
Specifications Defined by Industry convention
| Wire diameter (mm) | Stitch size (mm) | Roll width (mm) | Strand | Form |
|---|---|---|---|---|
| 0.10 | 1.5 x 2.5 | 40-600 | Single strand | Roll / sleeve |
| 0.15 | 2.0 x 3.0 | 40-600 | Single strand | Roll / sleeve |
| 0.20 | 3.0 x 4.0 | 40-600 | Single / double strand | Roll / sleeve |
| 0.23 | 4.0 x 5.0 | 40-600 | Single / double strand | Roll / sleeve |
| 0.28 | 5.0 x 6.0 | 40-600 | Double strand | Roll / sleeve |
Equivalent Standards
Where direct equivalents exist (ISO ↔ ASTM ↔ DIN), they are listed on the parent Knitted Wire Mesh page. Confirm against the specification table on this page — nominally equivalent documents can differ in tolerance limits.
When to Specify Industry convention
Choose Industry convention for international procurement and OEM supply where ISO documents are the contractual reference. It is the default modern specification for knitted wire mesh.
