19、(CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the system is to facilitate international trade by the harmonization of the
20、specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This European Standard w

General 1.1 Scope This specification applies to capacitors which will be connected to an a.c. mains or other supply with a nominal voltage not exceeding 1 000 V a.c. (r.m.s) or 1 000 V d.c. and with a nominal frequency not exceeding 100
40、 Hz. This specification prescribes tests which are appropriate when the suppression capacitor is to be connected to the supply mains. The relevant equipment specification may also prescribe other circuit positions where capacitors meeting the requirements of this specification shall be used. Combina
41、tions of two or more capacitors within one enclosure are included within the scope of this specification. Series resistor-capacitor combinations are within the scope of this specification provided that the resistor is in the same enclosure, and the resultant equivalent series resistance of the combi
42、nation does not exceed 1 k . Parallel resistor-capacitor combinations where the resistor acts as a discharge resistor for the capacitor are within the scope of this specification. Capacitors for special environmental conditions (e.g. drip-proof, splash-proof) may have to comply with additional requi
43、rements. NOTE For notes on the application of electromagnetic interference suppression capacitors see IEC-940. 1.2 Object The principal object of this specification is to prescribe preferred ratings and characteristics and to select from EN 130000, the appropriate quality assessment procedures, test
44、s and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification shall be of equal or higher performance level, because lower performance levels are not perm
45、itted. A further object of this specification is to provide a test schedule for safety approval. 1.3 Related documents ISO 3:1973, Preferred numbers Series of preferred numbers.
