19、NELEC Electronic Components Committee (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 internatio
20、nal trade by the harmonization of the 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 fur
21、ther testing. This European Standard was prepared by CECC WG 3, Capacitors. The text of the draft based on document CECC 32 400 was submitted to the formal vote: together with the voting report, circulated as document CECC(Sec)3457, it was approved by CECC as EN 132400 on 21 November 1993. The text
22、of EN 132400 is based on the following documents: CECC 32 400 Issue 1 (1992) and CECC(Sec) 3258/11.92 RV CECC(Sec) 3458/10.93.

General1 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
40、 100 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. Com
41、binations 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 c
42、ombination 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 r
43、equirements. NOTEFor 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, t
44、ests 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 p
45、ermitted. 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.
