This wire shall be either in the annealed and cold-drawn or oil-tempered condition as specified by the purchaser. 1.2 The values stated in either SI (metric) units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other.
