BS EN 10028-4:2017 EN 10028-4:2017 (E) 1Scope This European Standard specifies requirements for flat products for pressure equipment made of nickel alloy steels as specified in Table 1. The requirements and definitions of EN 10028-1:2017 also apply. NOTEOnce this European Standard is published in the EU official Journal (OjEU)under Directive 2014/68/EU presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this European Standard (Part 1 and the other relevant part 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 2014/68/EU are satisfied needs to be done. 2Normative references indispensable for its application.For dated references only the edition cited applies.For undated references the latest edition of the referenced document (including any amendments) applies.
