ASTM International Standard Specification for Welded Deformed Steel Bar Mats for Concrete Reinforcement ASTM A184/A184M-06(2011)

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.
