EN 131200:2002- 4 -1 General1.1 ScopeThis European Standard specifies requirements for fixed capacitors with metallized electrodes andpolypropylene dielectric. It specifies preferred ratings and characteristics and selects from EN 130000the appropriate quality assessment procedure, tests and measuring methods, and gives generalperformance requirements for this subfamily of capacitors.These capacitors may have “self-healing properties” depending on conditions of use. They are mainlyintended for use with direct voltage. Capacitors for alternating voltage and pulse applications will becovered by supplements to this document or a separate document.The maximum power to be applied is 500 var at 50 Hz and the maximum peak voltage is 2 500 V.Two performance grades of capacitors are covered by this specification, grade 1 for long-lifeapplication and grade 2 for normal application.Capacitors for direct connection to the supply mains to provide radio interference suppression are notincluded.1.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from otherpublications. These normative references are cited at the appropriate places in the text and thepublications are listed hereafter. For dated references, subsequent amendments to or revisions of anyof these publications apply to this European Standard only when incorporated in it by amendment orrevision. For undated references the latest edition of the publication referred to applies.EN 60062:1993Marking codes for resistors and capacitorsAmendment A1:1997EN 60068 SeriesEnvironmental testingEN 130000:1993General specification: Fixed capacitorsAmendments A1 to A10IEC 60063:1963Preferred number series for resistors and capacitorsAmendment 1:1967Amendment 2:1977ISO 3:1973Preferred numbers - Series of preferred numbers1.3 Information to be given in a detail specification1.3.1 GeneralDetail specifications shall be derived from the relevant blank detail specification.Detail specifications shall not specify requirements inferior to those of the generic, sectional or blankdetail specification.
