This Standard covers uncoated stress-relieved and low-relaxation smooth round wire, uncoated seven-wire stress-relieved and low-relaxation strand, and high-strength stress-relieved alloy steel bars used in prestressed concrete construction. All requirements are applicable to such wire, strand, and bars unless specifically stated otherwise.
This Standard covers uncoated stress-relieved and low-relaxation round high-carbon steel wire for use in prestressed concrete construction in button-head-type (cold-end-deformation) and wedge-type anchorage. The use of quenched and tempered wire shall not be permitted.
This Standard covers seven-wire, uncoated, stress-relieved and low-relaxation steel strand for use in pre-tensioned and post-tensioned pre-stressed concrete construction. The use of quenched and tempered wire shall not be permitted.
This Standard covers plain or deformed high-tensile strength alloy bars having a nominal diameter greater than 9 mm. The use of quenched and tempered bars shall not be permitted. Supplementary requirements of an optional nature are provided and they shall applyonly when specified by the purchaser.
