SLS 375: 2009 SPECIFICATION FOR RIBBED STEEL BARS FOR THE REINFORCEMENT OF CONCRETE
According to the BS4449:2005 and SLS 375:2009, reinforcing steel that produced using steel billets with fully known metallurgical history and all reinforcing steel batches shall be identifiable and traceable to verify their chemical composition of the steel billets used for the manufacturing of reinforcement against the product analysis. The following criteria for evaluation of conformity as per BS4449:2005 and SLS 375:2009 shall be followed when a supplier is selected.
The chemical composition and carbon equitant value
The results of the tensile and re-bend test of the product
Surface geometry
Further, upon delivering the reinforcing steel to the site following additional tests shall be carried out on the random test specimens selected from each lot for the verification of standard properties;
Re-bend Test nominal mass per meter and surface geometry one test unit per cast and nominal diameter.
Tensile Test one test piece per each 30t with at least three test pieces per nominal diameter.
