1.1 本规范涵盖用于预应力混凝土施工或预应力地锚的I型和II型高强度钢筋。I型钢筋表面平坦。II型钢筋具有表面变形。钢筋的最低抗拉强度水平为150 000 psi[1035 MPa]。 1.2 当买方要求进行钢筋弯曲试验时，提供了补充要求（S1）。补充要求仅在采购订单中规定时适用。 1.3 本规范的正文引用了提供解释材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本规范的要求。 1.4 本规范适用于以英寸-磅为单位的订单（作为规范 A722 )或使用国际单位制（作为规范 A722米 ). 1.5 以英寸-磅或国际单位制表示的数值应单独视为标准值。在文本中，国际单位显示在括号中。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。合并两个系统的值可能会导致不符合规范。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers Type I and Type II high-strength 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]. 1.2 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. 1.3 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. 1.4 This specification is applicable for orders in either inch-pound units (as Specification A722 ) or in SI units (as Specification A722M ). 1.5 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. 1.6 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.
