This British Standard specifies the requirements for annealed, or annealed and lightly drawn round steel wire, supplied in coils or straight lengths, suitable for the manufacture of mechanical springs by cold-forming which are hardened and tempered after forming.
It is generally applicable to wire sizes in the range from 1.00 mm to 16 mm.
