2 Standarder underlättar utvecklingen och höjer elsäkerheten Det finns många fördelar med att ha gemensamma tekniska regler för bl a säkerhet, prestanda, dokumentation, utförande och skötsel av elprodukter, elanläggningar och metoder. Genom att utforma sådana standarder blir säkerhetskraven tydliga och utvecklingskostnaderna rimliga samtidigt som marknadens acceptans för produkten eller tjänsten ökar. Många standarder inom elområdet beskriver tekniska lösningar och metoder som åstadkommer den elsäkerhet som föreskrivs av svenska myndigheter och av EU. SEK är Sveriges röst i standardiseringsarbetet inom elområdet svarar för standardiseringen inom elområdet i Sverige och samordnar svensk medverkan i internationell och europeisk standardisering. SEK är en ideell organisation med frivilligt deltagande från svenska myndigheter, företag och organisationer som vill medverka till och påverka utformningen av tekniska regler inom elektrotekniken. SEK samordnar svenska intressenters medverkan i SEKs tekniska kommittéer och stödjer svenska experters medverkan i internationella och europeiska projekt. Stora delar av arbetet sker internationellt Utformningen av standarder sker i allt väsentligt i internationellt och europeiskt samarbete. SEK är svensk nationalkommitté av International Electrotechnical Commission (IEC) och Comité Européen de Normalisation Electrotechnique (CENELEC). Standardiseringsarbetet inom SEK är organiserat i referensgrupper bestående av ett antal tekniska kommittéer som speglar hur arbetet inom IEC och CENELEC är organiserat. Arbetet i de tekniska kommittéerna är öppet för alla svenska organisationer, företag, institutioner, myndigheter och statliga verk. Den årliga avgiften för deltagandet och intäkter från försäljning finansierar SEKs standardiseringsverksamhet och medlemsavgift till IEC och CENELEC. Var med och påverka! Den som deltar i SEKs tekniska kommittéarbete har möjlighet att påverka framtida standarder och får tidig tillgång till information och dokumentation om utvecklingen inom sitt teknikområde. Arbetet och kontakterna med kollegor, kunder och konkurrenter kan gynnsamt påverka enskilda företags affärsutveckling och bidrar till deltagarnas egen kompetensutveckling. Du som vill dra nytta av dessa möjligheter är välkommen att kontakta SEKs kansli för mer information. Box Kista Tel

4 EN : Foreword The text of document 33/499/FDIS, future edition 1 of IEC , prepared by IEC/TC 33, "Power capacitors" was submitted to the IEC-CENELEC parallel vote and approved by CENELEC as EN :2012. The following dates are fixed: latest date by which the document has to be implemented at national level by publication of an identical national standard or by endorsement latest date by which the national standards conflicting with the document have to be withdrawn (dop) (dow) This document supersedes HD 597 S1:1992 (partially). EN :2012 includes the following significant technical changes with respect to HD 597 S1:1992: The standard has been split into different parts; Part 1 is the general rules and Parts 2, 3, 4 will be specific to the PLC, filters and dividers applications. The routine and type test have been reviewed and are presented in Figure 2. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights. This standard covers the Principle Elements of the Safety Objectives for Electrical Equipment Designed for Use within Certain Voltage Limits (LVD /95/EC). Endorsement notice The text of the International Standard IEC :2012 was approved by CENELEC as a European Standard without any modification. In the official version, for Bibliography, the following notes have to be added for the standards indicated: IEC NOTE Harmonized as EN IEC NOTE Harmonized as EN IEC NOTE Harmonized as EN ).
