This European Standard specifies the requirements for flat products for pressure equipments made of thermomechanically rolled steels as specified in Table 1. The steels are not suitable for hot forming. NOTE 1 At the time of publication of this European Standard, no sufficient data for the standardization of the elevated temperature properties of these steels was available. If their use at such temperatures is intended the conditions for this should be specially agreed between the interested parties. The requirements of EN 10028-1:2007 + A1:2009 also apply. NOTE 2 Once this European Standard is published in the EU Official Journal (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 97/23/EC is limited to technical data of materials in this European Standard (Part 1 and this Part 5 of the series) and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 97/23/EC are satisfied, needs to be done.
