DIN EN 10028-4:2009-09 EN 10028-4:2009 (E) 4 1 Scope This European Standard specifies requirements for flat products for pressure equipment made of nickel alloy steels as specified in Table 1. The requirements a
24、nd definitions of EN 10028-1:2007 + A1:2009 also apply. NOTE 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 t
25、his European Standard (Part 1 and this Part 4 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
26、 that the ESRs of Directive 97/23/EC are satisfied, needs to be done. 2 Normative references The following referenced documents are indispensable for the application of this document.
