1. Scope
1.1 This specification covers uncoated high-strength steel bars intended for use in prestressed concrete construction. Bars are of a minimum ultimate tensile strength level of 1035 MPa (150 000 psi).
1.2 Two types of bars are provided: Type I bar has a plain surface and Type II bar has surface deformations. The standard sizes and dimensions of Type I and II bars shall be those listed in Tables 1 and 2, respectively.
1.3 Supplementary requirements of an optional nature are provided. They shall apply only when specified by the purchaser.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
