Slide 1 Standards International European and National perspective Morten Andersen

Slide 2 Overview  Why standards?  International / European / National levels  Structure  National obligations  Implementation and withdrawal

Slide 3 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)

Slide 4 IEC standards  Basic safety publication –Guidlines for requirements for use by product standards e.g: Touch current IEC Insulation coordination IEC  Product standard –Basis for testing, certification –Country Notes –Reference to other standards e.g: Mains switch IEC Lasers IEC Protection against ingress of water IEC 60529

Slide 5 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

Slide 6 European standards National 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

Slide 7 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)

Slide 8 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

Slide 9 Implementation and withdrawal of European Standard  Example of dates for EN :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) –(dow) Latest date by which the national standards conflicting with the EN have to be withdrawn (dow)
