22、ess routes and surface finishes listed in Table 5. The general technical delivery conditions in EN 10021 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 Dire
23、ctive 97/23/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 standard against the design requirements of this specific item
24、of equipment to verify 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.
