ASTM A184/A184M-17

Standard Specification for Welded Deformed Steel Bar Mats for Concrete Reinforcement

ABSTRACT
This specification covers the standard guide for welded deformed steel bar mats for concrete reinforcement. Mats should be capable of withstanding static load exerted perpendicular to the plane of the mat tending to separate the bars with no apparent loosening when applied to one intersection of the connected bars. Tension tests shall be performed on the specimen to determine the conformance to reference test materials. Also, test of connections against separation shall be performed on an assembled mat by placing blocks under a deformed bar in the upper layer and applying the prescribed load upon the bar in the lower layer.
SCOPE
1.1 This specification covers material in mat (or sheet) form fabricated from deformed steel bars to be used for the reinforcement of concrete. Mats consist of two layers of bars that are assembled at right angles to each other. Mats are assembled by welding at the intersections.  
1.2 This specification is applicable for orders in either inch-pound units (as Specification A184) or SI units (as Specification A184M).  
1.3 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.  
1.4 This specification 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 specification to establish appropriate safety, health and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
