This European Standard specifies through thickness properties and associated test methods for flat products and sections of steel. This document may be applied as a supplement to all product standards for flat products and sections of fully killed steels, except stainless steels. It covers products having a thickness between 15 mm and 400 mm inclusive of steels with a specified minimum upper yield strength ReH or proof strength Rp0,2 d" 960 MPa1) for which improved through thickness properties are required. The application of this document to other steel types shall be the subject of agreement at the time of the order. The application of this document to products with thickness between 10 mm d" t <15 mm shall be the subject of agreement at the time of the order. See option 1. The application of this document to products with thickness t > 400 mm shall be the subject of agreement at the time of the order. See option 3.
