NOTE Once this European Standard is published in the EU Official Journal (OJEU) under Directive 97/23/EC, presumption of c
22、onformity 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 4 of the series) and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the te
23、chnical 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. 2 Normative references The following referenced documents are indispensable for the application of this docu
