HM42-2022 part 1
This specification covers two types of stress-relieved, round, high-carbon steel wire commonly used in prestressed linear concrete construction, as follows: Type BA wire is used for applications in which cold-end deformation is used for anchoring purposes (Button Anchorage), and Type WA wire is used for applications in which the ends are anchored by wedges, and no cold-end deformation of the wire is involved (Wedge Anchorage).
