3 DS/EN ISO :2006 Nationalt forord I pkt. 2.1 angives det, at andre dokumenter end dem, der er angivet under pkt. 2.2, kan anvendes, såfremt der er refereret til disse andre dokumenter i de produktstandarder, som produktet er fremstillet i henhold til, samt at de er teknisk ækvivalente. Flere standardiseringsorganisationer, fx DIN og DS, har opstillet en liste, der angiver europæiske standarder i forhold til de i standarden nævnte ISO-standarder. Den europæiske og internationale standardserie EN ISO 3834 anvender reference til ISO-standarder i kraft af den indgåede samarbejdsaftale mellem ISO og CEN. Idet man endnu ikke har nået det tilsigtede mål at udgive fælles ISO- og CEN-standarder for svejsning og NDT, forefindes der i dag fortsat selvstændige ISO- og EN-standarder med forskellige betegnelser. For nedennævnte ISO-standarder gælder følgende danske og europæiske standarder: ISO se DS/EN ISO 9712 se DS/EN 473 ISO se DS/EN 719 ISO se DS/EN 1418 ISO se DS/EN ISO se DS/EN 1435 ISO se DS/EN 970 ISO se DS/EN 1290 ISO se DS/EN 1321 ISO se DS/EN 1714 ISO/TR se DS/CEN/CR ISO ISO/TR se DS/EN ISO/TR se DS/CEN ISO/TR (da)

12 ISO :2005(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding. ISO 3834 consists of the following parts, under the general title Quality requirements for fusion welding of metallic materials: Part 1: Criteria for the selection of the appropriate level of quality requirements Part 2: Comprehensive quality requirements Part 3: Standard quality requirements Part 4: Elementary quality requirements Part 5: Documents with which it is necessary to conform to claim conformity to the quality requirements of ISO , ISO or ISO NOTE A Technical Report ISO/TR , Quality requirements for fusion welding of metallic materials Part 6: Guidance on implementing ISO 3834 is being prepared. Requests for official interpretations of any aspect of this part of ISO 3834 should be directed to the Secretariat of ISO/TC 44/SC 10 via your national standards body, a complete listing of which can be found at iv ISO 2005 All rights reserved

13 DS/EN ISO :2006 Forord ISO (the International Organization for Standardization) er en verdensomspændende sammenslutning af nationale standardiseringsorganisationer (ISO s medlemslande). Internationale standarder udarbejdes normalt af ISO s tekniske komitéer. Hvert medlemsland, som er interesseret i et emne, inden for hvilket der er oprettet en teknisk komité, har ret til at være repræsenteret i den pågældende komité. Internationale organisationer, både statslige og ikkestatslige, der har en samarbejdsaftale med ISO, deltager ligeledes i arbejdet. ISO samarbejder tæt med IEC (the International Electrotechnical Commission) i alle anliggender vedrørende elektroteknisk standardisering. Internationale standarder udarbejdes i henhold til reglerne i ISO/IEC Directives, Part 2. Tekniske komitéers væsentligste opgave er at udarbejde internationale standarder. Forslag til internationale standarder, der er godkendt af de tekniske komitéer, sendes ud til medlemslandene til afstemning. Offentliggørelse som international standard kræver godkendelse fra mindst 75 % af de medlemslande, som afgiver deres stemme. Der gøres opmærksom på muligheden for, at dele af denne internationale standard kan være genstand for patentrettigheder. ISO kan ikke drages til ansvar for at identificere sådanne rettigheder. ISO er udarbejdet af teknisk komité ISO/TC 44, Welding and allied processes, underkomité SC 10, Unification of requirements in the field of metal welding. ISO 3834 består af følgende dele under den generelle titel: Quality requirements for fusion welding of metallic materials: Part 1: Criteria for the selection of the appropriate level of quality requirements Part 2: Comprehensive quality requirements Part 3: Standard quality requirements Part 4: Elementary quality requirements Part 5: Documents with which it is necessary to conform to claim conformity to the quality requirements of ISO , ISO or ISO NOTE En teknisk rapport ISO/TR , Quality requirements for fusion welding of metallic materials Part 6: Guidance on implementing ISO 3834, er under udarbejdelse. Anmodninger om officielle fortolkninger i enhver henseende af denne del af ISO 3834 bør sendes til sekretariatet for ISO/TC 44/SC 10 via det nationale standardiseringsorgan.
