Organization: ASTM
Publication Date: 10 September 2002
Status: inactive
Page Count: 4
ICS Code (Steel wire, wire ropes and link chains): 77.140.65
ICS Code (Steels for reinforcement of concrete): 77.140.15
scope:

This specification covers two types of uncoated 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 application in which the ends are anchored by wedges, and no cold-end deformation of the wire is involved (Wedge Anchorage).

Supplement I describes low relaxation wire and relaxation testing for that product.

The values stated in either inch-pound or SI units are to be regarded as standard. Within the text, the inch-pound units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other, without combining values in any way.
