26、nesses given in Table 5. The general technical delivery conditions in EN 10021 also apply to products supplied in accordance with this European Standard. NOTE Once this European Standard is published in the Official Journal of the European Union (OJEU) under Directive 2014/68/EC, presumption of conf
27、ormity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EC is limited to technical data of materials in this European Standard 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 sta
28、ndard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done. . 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensab
