FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
publishes International Standards.
electronic fields. To this end and in addition to other activities, the IEC
Their preparation is entrusted to technical committees; any IEC National Committee interested in
the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of the IEC on technical matters, express as nearly as possible an
international consensus of opinion on the relevant subjects since each technical committee has
representation from all interested National Committees.
have the form of recommendations for international use and are published in the
3) The documents produced
form of standards, technical reports or guides and they are accepted by the National Committees in that
sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the la tter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the
subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 831-2 has been prepared by 1EC technical committee 33:
Power capacitors.
This second edition cancels and replaces the first edition which was issued as a technical
in 1988. It constitutes a technical revision and now has the status of an Inter-
repo rt
national Standard.
The text of this standard is based on the following documents:

1 Scope
This part of IEC 831 applies to capacitors according to IEC 831-1 and gives the require-
ments for the ageing test, self-healing test and destruction test for these capacitors.
NOTE – The numbering of the clauses and subclauses in this standard corresponds to that of IEC 831-1.
2 Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this part of IEC 831. At the time of publication, the editions
indicated were valid. All normative documents are subject to revision, and parties to
of IEC 831 are encouraged to investigate the possibility of
agreements based on this pa rt

Section 2: Quality requirements and tests
17 Ageing test
17.1 Conditioning
The temperature of the case during the ageing test shall be the highest mean temperature
in 24 h (see table I, IEC 831-1) plus the difference between the measured temperature of
the case and the cooling air temperature recorded at the end of the thermal stability test
carried out on an identical unit.
The two test methods indicated below are intended to ensure that the capacitor case
temperature is maintained constant during the test.
The two methods are considered as being equivalent.
The units that are not sealed shall be tested in air, with forced circulation.
Testing in air with forced circulation
17.1.1
The capacitor unit is mounted in an enclosure in which heated air is circulated with an air
velocity such that temperature variations at any point of the enclosure do not exceed
±2 °C. The sensitive element of the thermostat regulating the temperature in the capacitor
enclosure shall be located on the surface of the capacitor container, three-quarters of the
way up.
The capacitor shall be placed in a vertical position with the terminals upright.
When many capacitors are tested together, they shall be placed with sufficient clearance
between them in order to have sufficient temperature uniformity.
After placing the capacitor in the unheated enclosure, the thermostat shall be set at a
temperature equal to that indicated in 17.1.
Then, without energizing the capacitor, the enclosure shall be brought to thermal stability,
which shall be deemed to have been reached when the container temperature of the
±2
°C.
capacitor has reached the stated temperature with a tolerance of
The capacitor shall then be energized at the voltage stated in item a) of 17.2.
17.1.2 Testing in a liquid bath
The capacitor unit is immersed in a container filled with a liquid which, by appropriate heat-
ing, is kept at the temperature indicated in 17.1 during the
