Standards International European and National perspective 2010-07-01 Morten Andersen
Overview • Why standards? • International / European / National levels • Structure • National obligations • Implementation and withdrawal
Standardization organizations International/European/National • IEC (International Electrotechnical Commission) • CENELEC (Comitè Europèen de Normalisation Electrotecnique) • National Electrotechnical Committes Norway: NEK (Norwegian Electrotechnical Committe Relation IEC EN Standards • ITU (International Telecommunication Union) • ETSI (European Telecommunications Standards Institute) • ISO (International Organization for Standardization)
IEC standards • Basic safety publication • Guidlines for requirements for use by product standards e.g: • Touch current IEC 60990 • Insulation coordination IEC 60664 • Product standard • Basis for testing, certification • Country Notes • Reference to other standards e.g: • Mains switch IEC 61058 • Lasers IEC 60825 • Protection against ingress of water IEC 60529
European Standards (EN)Structure • COMMON MODIFICATIONS (CM) • Common CENELEC modifications to the reference document (IEC standard) • SPECIAL NATIONAL CONDITIONS (SNC) • National characteristic or practice that cannot be changed even over a long period, e.g. climatic conditions, electrical earthing conditions. If it affects harmonization, it forms part of the EN • NATIONAL DEVIATIONS (ND) • National deviation (A-deviation) due to regulations, the alteration of which is for the time being outside the competence of the CENELEC member
European standardsNational obligations vs EN - HD - ENV • EN - European standard • Is to be implemented as identical National standard or by endorsement • HD - Harmonization Document • Not obliged to implement as National standard (National Committee to decide) • Is to be announced and made available • ENV - European preStandard • No obligations • Limited lifetime 3 years
Relation between IEC- and EN-standards The drawing shows how the standards are linked together. - Testing for IEC (without Group/National differences): A - Testing for IEC (with Group/National differences): A + B - Testing for Europe (with national deviations and conditions): A + C - Testing for IEC, Europe (with Group/National differences): A + B + C IEC standard (A) Group/National differences (CB bulletin) (B) EN standard(C)
Implementation and withdrawal of European Standard • CENELEC dates of EN`s; dor:Date of Ratification doa:Date of Announcement dop: Date of Publication dow: Date of Withdrawal
Implementation and withdrawal of European Standard • Example of dates for EN 60950-1:2006 • (dop) Latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2006-12-01 • (dow) Latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2010-12-01
