CEN/TC 459/SC 4/WG 4 - Pre-stressing steels

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.
