ISO 4032 is the governing dimensional standard for wire rope. This page sets out the scope of the standard, reproduces the full size table it specifies, and lists the DIN/ISO/ASME cross-references commonly cited in datasheets and drawings.
ISO 4032 — Scope
ISO 4032 specifies the dimensions and tolerances of wire rope — gb/t 6170 / iso 4032 (series 063). 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 4032, alongside the related GB/T 6170 / ISO 4032 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 4032
| Nominal diameter (mm) | Construction | Min breaking force (kN) | Mass (kg/100m) | Material | Reference standard |

Companion Standards
ISO 4032 controls only the geometry of wire rope — gb/t 6170 / iso 4032 (series 063). The mechanical strength is set by ISO 898-1 (bolts and screws) or ISO 898-2 (nuts); the surface finish is governed by separate finish standards (e.g. ISO 4042 for electroplating). For corrosion testing, the relevant document is ISO 9227 (neutral salt spray).
When to Specify ISO 4032
Choose ISO 4032 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for wire rope — gb/t 6170 / iso 4032 (series 063).
