ASTM A722/A722M-18 预应力混凝土用高强度钢筋的标准规范

1.1 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]. 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.

ASTM A970/A970M-18 钢筋混凝土钢筋标准规范

1.1 This specification covers deformed steel reinforcing bars in cut lengths, with a head attached to one or both ends, for concrete reinforcement. Heads are forge-formed, machined from bar stock, or cut from plate. Attachment can be accomplished through: 1.1.1 Welding; 1.1.2 Integrally hot forging of a head from the reinforcing bar end; 1.1.3 Internal threads in the head mating to threads on the bar end; 1.1.4 Cold-swaging an externally threaded coupling sleeve onto the reinforcing bar; 1.1.5 Cold-extruding an external coupling sleeve onto the reinforcing bar; 1.1.6 Cold-swaging an external coupling sleeve or headed sleeve onto the reinforcing bar; 1.1.7 Attaching a coupling sleeve to the end of the reinforcing bar by means of the means of a ferrous-filler medium; or 1.1.8 Separate threaded nut to secure the head to the bar. NOTE 1—The requirements of this specification are only applicable to headed bars where the attachment of the head is accomplished by one of the methods listed in 1.1. 1.2 Limitations on head dimensions and on obstructions and interruptions of bar deformations on the non-planar features on the bearing face of the head are presented in Annex A1. The requirements in Annex A1 only apply when specified by the purchaser (see 4.2.3). 1.3 This specification is applicable for orders in either inch-pound units as Specification A970 or SI units as Specification A970M. 1.4 The values stated in either inch-pound units 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. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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.

ASTM A820/A820M-16 纤维增强型混凝土用钢纤维的标准规格

1.1 This specification covers minimum requirements for steel fibers intended for use in fiber-reinforced concrete. Five types of steel fibers for this purpose are defined as pieces of smooth or deformed cold-drawn wire; smooth or deformed cut sheet; melt-extracted fibers; mill-cut or modified cold-drawn wire steel fibers that are sufficiently small to be dispersed at random in a concrete mixture. 1.2 This specification provides for measurement of dimensions, tolerances from specified dimensions, and required minimum physical properties, and prescribes testing procedures to establish conformance to these requirements. 1.3 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of a conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by the waiving of a test requirement or by making a test requirement less stringent. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
