26 FOREWORD
28 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all
29 national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international
30 cooperation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition
31 to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees;
32 any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International,
33 governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
34 collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions
35 determined by agreement between the two organizations.
36 2) The formal decisions or agreements of the IEC on technical matters, express as nearly as possible an international consensus
37 of opinion on the relevant subjects since each technical committee has representation from all interested National Committees.
38 3) The documents produced have the form of recommendations for international use and are published in the form of
39 standards, technical reports or guides and they are accepted by the National Committees in that sense.
40 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards
41 transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC
42 Standard and the corresponding national or regional standard shall be clearly indicated in the latter.
43 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
44 declared to be in conformity with one of its standards.
45 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent
46 rights. IEC shall not be held responsible for identifying any or all such patent rights.
48 International Standard IEC 60931-2 has been prepared by IEC by technical committee 33: Power
49 capacitors and their applications.
50 The text of this standard is based on the following documents:
DIS Report on voting
33/XXX/FDIS 33/XXX/RVD
52 Full information on the voting for the approval of this standard can be found in the report on voting
53 indicated in the above table.
54 This third edition cancels and replaces the second edition which was issued as an IEC standard
55 in 1995. It constitutes a technical revision and now has the status of an International Standard.

67 1 Scope
68 This part of IEC 60931 applies to capacitors according to IEC 60931-1 and gives the requirements
69 for the ageing test and destruction test for these capacitors.
70 NOTE The numbering of the clauses and subclauses in this part corresponds to that of IEC 60931-1.

82 6.12 Ageing test
83 6.12.1 Conditioning
84 6.12.1.1 General
85 The temperature of the case during the first part (6.12.2 a) and the third part (6.12.2 c) of the ageing
86 test shall be the highest mean temperature in 24 h (see IEC 60931-1, table 1) plus the difference
87 between the measured temperature of the case and the cooling air temperature recorded at the end
88 of the thermal stability test carried out on an identical unit. The second part (6.12.2 b)) of the ageing
89 test should be performed at room temperature.
90 The two test methods indicated below are intended to ensure that the capacitor case temperature is
91 maintained constant during the test.
92 The two methods are considered as being equivalent.
93 The units that are not sealed shall be tested in air, with forced circulation.
94 6.12.1.2 Testing in air with forced circulation
95 The capacitor unit is mounted in an enclosure in which heated air is circulated with an air velocity
96 such that tempe
