ECISS/TC 19 - Concrete reinforcing and prestressing steels - Properties, dimensions, tolerances and specific tests

This document specifies general requirements and definitions for the performance characteristics of weldable reinforcing steel used for the reinforcement of concrete structures, delivered as finished products in the form of:
-   bars, coils (rod, wire) and de-coiled products;
-   sheets of factory-made machine-welded fabric;
-   lattice girders.
1.2   Steels according to this document have a ribbed, indented or smooth surface.
1.3   This document does not apply to:
-   non-weldable reinforcing steel;
-   galvanized reinforcing steel;
-   epoxy-coated reinforcing steel;
-   corrosion resistant reinforcing steel;
-   prestressing steels (see prEN 10138-1 to -4);
-   indented strip;
-   further processing, e.g. cutting or cutting and bending.

ISO 15630-1:2010 specifies test methods applicable to reinforcing bars, wire rod and wire for concrete.

ISO 15630-3:2010 specifies test methods applicable to prestressing steels (bar, wire or strand) for concrete.

ISO 15630-2:2010 specifies test methods applicable to welded fabric for the reinforcement of concrete.

This European Prestandard specifies requirements for the chemical composition and the mechanical and geometrical properties of weldable ribbed reinforcing steel in grade B500, categories A and B (designated as steels B500A and B500B, see table 1) used for the reinforcement of concrete structures in the form of - bars and coils or as elements for the manufacturing of welded fabric, - sheets of factory made machine welded fabric in the diameter ranges given in table 1.
