NBN EN 10028-3:2009

This European Standard specifies requirements for flat products for pressure equipment made of weldable fine
grain steels as specified in Table 1.
NOTE 1 Fine grain steels are understood as steels with a ferritic grain size of 6 or finer when tested in accordance with
EN ISO 643.
The requirements and definitions of EN 10028-1 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 3 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.
