ISO covers the dimensional requirements for wire rope. Reproduced below: the complete size table, the tolerance grades, and the companion and equivalent standards referenced when ordering to this document.
ISO — Scope
ISO specifies the dimensions and tolerances of wire rope — iso / din (series 152). Material, property class, surface finish and packaging are governed by separate documents in the same standards family (for example ISO 898-1 for the mechanical property classes of bolts and screws).
Tolerance & Product Grades
ISO, alongside the related ISO / DIN entries on this site, specifies product grades (typically A or B for fine work and C for general engineering) and tolerance classes for the controlling dimensions. Choose the grade against the precision your application requires.
Dimensions Specified by ISO
| Nominal diameter (mm) | Construction | Min breaking force (kN) | Mass (kg/100m) | Material | Reference standard |
|---|---|---|---|---|---|
| 4 | 6x7 | 8.95 | 5.85 | Galvanized steel | GB/T 20118 / ISO 2408 |
| 5 | 6x7 | 13.4 | 8.94 | Galvanized steel | GB/T 20118 / ISO 2408 |
| 6 | 6x19 | 17.6 | 13.0 | Galvanized steel | GB/T 20118 / ISO 2408 |
| 8 | 6x19 | 31.3 | 23.0 | Galvanized steel | GB/T 20118 / ISO 2408 |
| 10 | 6x19 | 48.5 | 36.0 | Galvanized steel | GB/T 20118 / ISO 2408 |
| 12 | 6x19 | 69.5 | 52.0 | Galvanized steel | GB/T 20118 / ISO 2408 |
| 16 | 6x37 | 119 | 89.0 | Galvanized steel | GB/T 20118 / ISO 2408 |
| 20 | 6x37 | 185 | 138.0 | Galvanized steel | GB/T 20118 / ISO 2408 |
| 24 | 6x37 | 265 | 196.0 | Galvanized steel | GB/T 20118 / ISO 2408 |
Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Wire Rope — ISO / DIN (Series 152) page. Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
When to Specify ISO
Choose ISO for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for wire rope — iso / din (series 152).
