Standard Specification for Uncoated Stress-Relieved Steel Wire for Prestressed Concrete — 3 стр.
Область применения

1.1 This specification covers two types of uncoated stress-relieved round high-carbon steel wire commonly used in prestressed linear concrete construction, as follows:

1.1.1 Type BA wire is used for applications in which cold-end deformation is used for anchoring purposes (Button Anchorage), and

1.1.2 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).

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

1.3 The values stated in inch-pound units are to be regarded as the standard.
