Abstract

Overview

ISO 23213:2022 - Carbon steel wire for bedding and seating springs - specifies requirements for cold-drawn, round carbon steel wire supplied in the uncoated condition for manufacture of springs used in bedding and seating in the automotive and furniture industries. The standard defines classification, dimensional and mechanical requirements, testing, inspection, packing and marking to ensure consistent spring performance and interchangeability.

Key Topics and Requirements

Scope & classification
- Applicable nominal diameters: 0.80 mm to 6.00 mm.
- Five wire types (I–V) for different spring applications (e.g., pocket, Bonnell, link, edging, sinuous) with recommended diameter ranges.
Diameter, tolerance & geometry
- Diameter measured as mean of two orthogonal micrometer readings; specified tolerances vary by diameter range (examples provided in the standard).
- Ovality limits, wire cast (circular and helix cast) and tip rise requirements are specified.
Mechanical properties
- Tensile strength requirements given by type and diameter (detailed ranges for Types I–V).
- Maximum tensile range variation within a batch: 150 MPa.
Forming tests
- Wrapping test (ISO 7802) for wire
