About This Item

 

Full Description

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.
