Standard Specification for Tin-Coated Soft or Annealed Copper Wire for Electrical Purposes

This specification covers tinned, round, soft, or annealed copper wire for electrical purposes. The tinned wire shall conformto the required tensile strength and elongation. Electrical resistivity shall be measured. The wire sizes shall be expressed as the diameter of the wire and shall be measured using micrometre caliper equipped with a vernier. The tin coating shall be continuous. The continuity of the wire shall be determined on representative samples taken before stranding or insulating. The continuity of tinning shall be determined by the hydrochlroic acid-sodium polysulfide test. The tin coating shall be firmly adherent to the surface of the copper. The adherence of coating on the wire shall be determined on representative samples taken before stranding or insulating. The adherence of coating shall be determined by the wrapping and immersion test.
