Standard Specification for High-Strength Steel Bars for Prestressed Concrete
|Publication Date:||1 September 2018|
|ICS Code (Steels for reinforcement of concrete):||77.140.15|
This specification covers Type I and Type II highstrength steel bars intended for use in prestressed concrete construction or in prestressed ground anchors. Type I bars have a plain surface. Type II bars have surface deformations. Bars are of a minimum tensile strength level of 150 000 psi [1035 MPa].
A supplementary requirement (S1) is provided for use where bend tests of bars are required by the purchaser. The supplementary requirement applies only when specified in the purchase order.
The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
This specification is applicable for orders in either inch-pound units (as Specification A722) or in SI units (as Specification A722M).
The values stated in either inch-pound or SI units are to be regarded separately as standard.Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
