The following dates were fixed: For products which have complied with the relevant national standard before1993-12-01, as shown by the manufacturer or by a certi
20、fication body, this previous standard may continue to apply for production until 1998-12-01. Annexes designated “normative” are part of the body of the standard.

23、d states the requirements for both self-healing and non-self-healing continuously rated a.c. capacitors of up to and including2,5kvar, and not less than0,14F, having a rated voltage not exceeding1000V, which are intended for use in discharge lamp circuits 1)operating at50Hz or60Hz and at altitudes u
24、p to3000m. It covers capacitors intended for connection in shunt or in series with the lamp circuit or an effective combination of these. It covers only impregnated or unimpregnated capacitors, having a dielectric of paper, plastic film or a combination of both, either metallized or with metal foil
25、electrodes. This standard does not cover radio-interference suppressor capacitors the requirements for which are found in IEC384-14. Tests in this standard are type tests. Guidance on conformity of production is given in Annex A. 1.2 Normative references The following standards contain provisions wh
26、ich, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibilit
27、y of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

General and safety requirements. 2 Definitions For the purposes of this International Standard, the definitions of IEC1048 shall apply. 3 General notes on tests All capacitors specified in this standard shall comply with the requirements of IEC1
30、048. Tests according to this standard are type tests. NOTEThe requirements and tolerances permitted by this standard are related to testing of a type test sample submitted for that purpose. In principle, this type test sample should consist of units having characteristics typical of the manufacturer
31、s production and be as close to the production centre points as possible. It may be expected with the tolerances given in the standard that products manufactured in accordance with the type test sample will comply with the standard for the majority of the production. Due to the production spread, it
32、 is inevitable, however, that there may be products outside the specified tolerances. For guidance on sampling plans and procedures for inspection by attributes, see IEC410. Capacitors shall be subjected to the tests detailed in clause4. Unless otherwise specified, tests shall be carried out at a te
33、mperature of20C5C, using where appropriate a voltage source as detailed inAnnex B. Test temperatures specified in particular clauses shall be subject to a tolerance of 2 C, unless otherwise stated. 1) These lamps and associated ballasts are covered in the specifications of the following IEC publicat

Performance requirements.EN 61049:1993 4 BSI 04-1999 Unless otherwise specified, the type shall be deemed to comply with any
36、 one clause if not more than one failure occurs in the test of that clause. If three or more failures occur, the type shall be rejected. If two failures occur in any one test, that test, and any preceding tests which may have influenced the test results, shall be repeated on the same quantity of cap
37、acitors and if any further failures occur, the type shall be rejected. For a range of capacitors of the same construction, rated voltage and cross-sectional shape, each group referred to in clause4 shall contain as nearly as possible equal numbers of capacitors of the highest capacitance and the low
38、est capacitance in that range. Moreover, the manufacturer shall provide data on the ratio of capacitance per area outer total surface of the container of each capacitance value in the range. The capacitor with the maximum capacitance per unit surface area shall also be tested if this ratio exceeds t
39、hat of the maximum capacitance value in the range by10% or greater. Similarly, the capacitor with the minimum capacitance per unit area shall also be tested if the ratio is less than that of the minimum capacitance value in the range by10% or greater. “Area” denotes total outer surface area of capac
40、itor case ignoring small protrusions, terminals and fixing studs. With this procedure the tests qualify all intermediate values of capacitance in the range. NOTE 1The “same construction” includes for example the same dielectric material, dielectric thickness and type of case (metal or plastic). NOTE
41、 2“Cross-sectional shape” means: round, rectangular, oval, etc. 4 Testing sequence A total of47 non-self-healing capacitors, or in the case of self-healing types52 capacitors, shall be taken and divided into four groups as indicated below. NOTEFor capacitors above1kvar the quantities for testing can
42、 be agreed between manufacturer and testing authority. The following initial test shall be applied to all the capacitors: capacitance measurement in accordance with clause6. The first group of5 capacitors shall be subjected to the test for deviation of capacitance with temperature in accordance with
43、 clause7. The second group of5 capacitors, completed with the5 capacitors of the first group, shall be subjected to the self-healing test in accordance with clause16. This test is only applicable for self-healing capacitors. The third group of21 capacitors shall be subjected to the endurance test in
44、 accordance with clause8. The fourth group of21 capacitors shall be retained as spares in the event of a repeat test being necessary in the first three groups. 5 Marking The marking requirements of IEC1048 shall apply, together with the following. 5.1 Period of manufacture, which may be in code form
45、. 5.2 For unimpregnated metallized plastic film shunt capacitors of250V rated voltage or less, with a t cnot higher than85C, the letter “D”. 6 Capacitance The capacitance of each capacitor when measured at50Hz or60Hz, as appropriate, shall be within the tolerance limits marked on the capacitor. Capa
46、citance shall be measured using a method which excludes errors due to harmonics. The accuracy of measurement shall be better than0,25% of the capacitance measured. The measuring voltage shall not be higher than the rated voltage of the capacitor; the frequency shall be as near as possible to the rat
47、ed frequency. Measurement at other frequencies is allowed, provided that the frequency dependence of the capacitance is very small. The measured capacitance shall not deviate from the rated capacitance by more than the tolerance marked on the capacitor. Compliance is checked by measurement.EN 61049:
48、1993 BSI 04-1999 5 7 Change of capacitance with temperature The change of capacitance with temperature shall stay within acceptable limits. Compliance is checked by the tests of7.1 to7.6. 7.1 Measurements of capacitance shall be made under the conditions prescribed in clause6. 7.2 The capacitor shal
49、l be measured at each of the following temperatures in turn: a) 20C 2C; b) rated minimum temperature 3C (C T min ); c) 20C2C; d) rated maximum temperature2C (C T max ); e) 20C 2C. 7.3 Capacitance measurements shall be made at each of the temperatures specified in7.2 after the capacitor has reached thermal stability. The measuring voltage shall be applied only for the minimum time necessary to make the capacitance measurements. The condition of thermal stability shall be judged to have been reached when two readings of capa
