AS 2266:2002 pdf download.Carbon steel spring wire for bedding and seating.

3.3 Cast

The form taken by the indiidual waps (rings, turns or circles) of a ss ire within a coil.

NOTE: When a wap is cut from a coil of bedding or seating spring wire. it freely assumes a geometrical shape. or cast,

characterized, for block-wound coils, by overall diameter of the wap and helical separation of its cut cnds or. by agreement

between manufacturer and purchaser, by a nominally straight-line (or rectilineart formation,

3.4 Cast analysis

Analysis determined, for such clcmcnts as have been specified, on a test sample obtained during the pouring of the liquid steel;

also known as heat analysis.

3.5 Coil

A continuous length of wire, neatly and compactly wound, and containing no mechanical joints (such as knots), but may contain

electric resistance butt-welds: it may be supplied unsupported. being in the general form of a torus (quoil hapc). or it may be

supplied supported on a transportable carrier (scc Clause 4.5).

3.6 Hard-drawn

Carbon steel wire cold-worked by drawing with a minimum of 40% reduction of cross- sectional area from a heat-treated (patented or similar process) base.

The difference between the masimum and minimum diameters of the wire. measured at the same cross-section; also known as

out-of-roundness.
