-   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);

This document does not cover the sampling conditions that are dealt with in the product standards.

This document specifies the requirements for uncoated high strength steel strands or zinc or zinc alloy coated high strength steel strands, encapsulated with wax and a sheath for construction applications.
The document applies only to products as supplied by the manufacturer.

1.1   This document specifies general requirements and definitions for the essential characteristics of weldable reinforcing steel used for the reinforcement of concrete structures, delivered as finished products in the form of:
-   bars (including those produced by the reinforcing steel manufacturer from coil);
-   coils;
-   sheets of factory-made machine-welded fabric;
-   lattice girders.
1.2   Steels according to this document have a ribbed, indented or smooth surface.
NOTE 1   The protrusions between indentations of indented reinforcing steel have the same function as transverse ribs of ribbed reinforcing steel. There is no definition which specifies the difference between ribbed and indented surface geometry. Therefore, in this document, the same bond parameters are used for ribbed and indented steel.
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;
-   indented strip;
-   further processing by a processor, e.g. de-coiling/straightening, cutting or cutting and bending.
NOTE 2   Further processing could influence some essential characteristics of the product.

This document specifies the requirements and definitions for the essential characteristics of prestressing bars, which are used for the prestressing of concrete and which are delivered as finished products in the form of:
-   hot rolled and processed bars;
-   plain and threaded bars.
NOTE 1   The specification of manufacturing processes related to the finished product is required to ensure that the essential characteristics can be tested properly and that test results are valid. It is not possible to anticipate that any other manufacturing process leads to products which can be tested properly with the specified test methods. Thus, a conclusion to the safe application in building construction would not any longer be possible for those products.
This document does not apply to:
-   galvanized steel;
-   epoxy coated steel;
-   reinforcing steel (see EN 10080);
-   further processing.
NOTE 2   Example for further processing: Plain bars are also applied in systems for the prestressing of concrete with threaded ends. The threaded ends depend in length and type on the intended use of the system and are manufactured downstream in the supply chain.

This document specifies product characteristic test/assessment method and the way of expressing test results for stainless steel as defined in EN 10088-1:2014 and designated as in EN 10088-1:2014 for the use of the reinforcement of concrete.
It applies to stainless steel products with ribbed or indented surfaces, which are in the form of:

NOTE   The protrusions between indentations of indented reinforcing steel have the same function as transverse ribs of ribbed reinforcing steel. There is no definition, which specifies the difference between ribbed and indented surface geometry. Therefore, in this document, the same bond parameters are used for ribbed and indented steel.
