M/115 REV - Steel for concrete

This Standard is applicable for the design of structural or self supporting systems made of sandwich panels with steel faces and core material with a Declaration of Performance (according to EN 14509-1 and -2) used as internal and external walls, roofs and ceilings.

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:
-   bars and coils (rod, wire);
-   sheets of factory-made machine-welded fabric;
-   lattice girders and hybrid lattice girders composed by stainless steel and by weldable reinforcing steel according to prEN 10080:2023.
Steels according to this document have a ribbed, indented or smooth surface.
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.
This document does not apply to:
-   pre-stressed stainless steels;
-   indented strip;
-   stainless steel tube filled with carbon steel swarf, which is then hot or cold reduced;
-   stainless steel smooth bar with weld material deposited on it;
-   galvanized reinforcing steel;
-   epoxy-coated reinforcing steel.
