10 EN :2007+A1:2009 (E) 1 Scope This European Standard specifies general technical delivery conditions for flat products for the construction of pressure equipment. The general technical delivery conditions in EN 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 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 97/23/EC are satisfied, needs to be done. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

11 DS/EN A1 + AC: Anvendelsesområde Denne europæiske standard fastlægger generelle tekniske leveringsbetingelser for flade produkter beregnet til fremstilling af trykbærende udstyr. Derudover gælder de generelle tekniske leveringsbetingelser i EN NOTE Når denne europæiske standard er blevet omtalt i Den Europæiske Unions Tidende (EUT) under direktiv 97/23/EF, er formodningen om overensstemmelse med de væsentlige sikkerhedskrav i direktiv 97/23/EF begrænset til tekniske data for materialer i denne europæiske standard (del 1 og den relevante anden del af serien), og det kan ikke formodes, at materialet dermed er egnet til et specifikt stykke udstyr. Det er derfor nødvendigt at vurdere de tekniske data i denne materialestandard i forhold til konstruktionskravene til dette specifikke stykke udstyr for at verificere, at de væsentlige krav i direktiv 97/23/EF er opfyldt. 2 Normative referencer Følgende dokumenter er nødvendige for anvendelsen af dette dokument.
