GENERAL AND SAFETY REQUIREMENTS


FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). 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. 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 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 IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This International Standard has been prepared by subcommittee 34C: Auxiliaries for lamps, of
IEC technical committee 34: Lamps and related equipment.
This second edition cancels and replaces the first edition published in 1991 and its amend-
ments 1 (1995) and 2 (1999). It constitutes a technical revision. In this new edition conformity
of production has been changed from “informative” to “normative”, thus providing a higher
degree of safety for capacitors.

OTHER DISCHARGE LAMP CIRCUITS –
GENERAL AND SAFETY REQUIREMENTS



1 Scope
This International Standard states the requirements for both self-healing and non-self-healing
continuously rated a.c. capacitors of up to and including 2,5 kVAr, and not less than 0,1 µF,
having a rated voltage not exceeding 1 000 V, which are intended for use in discharge lamp
circuits operating at 50 Hz or 60 Hz and at altitudes up to 3 000 m.
NOTE These lamps and associated ballasts are covered by IEC 60081, IEC 60901, IEC 60188, IEC 60192,
IEC 60662, and IEC 61167 and by IEC 61347-2-8 and IEC 61347-2-9, respectively.
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 electrodes.
This standard does not cover radio-interference suppressor capacitors the requirements for
which are found in IEC 60384-14.
Tests given in this standard are type tests. Requirements for testing individual capacitors
during production are not included.

4 General requirements
Capacitors shall be so designed that in normal use they function safely and cause no danger
to persons or surroundings.
All exposed metal parts shall be constructed of non-ferrous material or shall be protected
against rusting. Visible rust shall not occur. The test of Clause 15 will show whether the
capacitor is sufficiently protected against rust.
Tests for checking the mechanical robustness are under consideration.
Compliance with the requirements of Clauses 4 to 11 is checked by measurement, inspection
and by carrying out all the tests specified in this standard.
NOTE In Japan an additional capacitor type is permitted, details of which are to be found in JIS C 4908. Inclusion
of the requirements for these capacitors in this standard is under consideration.
5 General notes on tests
Tests according to this standard are type tests, (Annex C excluded).
NOTE The requirements and tolerances permitted by this standard are related to testing of a type test sample
submitted for that purpose. Compliance of the type test sample does not ensure compliance of the whole
production of a manufacturer with this safety standard. Conformity of production is the responsibility of the
manufacturer and includes routine tests and quality assurance in addition to type testing.
Capacitors shall be subjected to the tests detailed in Clause 12.
Unless otherwise specified, tests shall be carried out at a temperature of (20 ± 5) °C, using
where appropriate a voltage source as detailed in Annex A.
Test temperatures specified in particular clauses shall be subject to a tolerance of ±2 °C,
unless otherwise stated.
Unless otherwise specified, the type shall be deemed to comply with any one clause or
subclause if not more than one failure occurs in the test of that clause or subclause. 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 capacitors and if any further failures occur, the type shall be rejected.
NOTE A repeat test may be permitted only once in a series of tests according to the requirements of this
standard. A repeat test is not permitted in the destruction test, Clause 18, in the case of a catastrophic failure.
For a range of capacitors of the same construction, rated voltage and cross-sectional shape,
each group referred to in Clause 12 shall contain as nearly as possible equal numbers of
capacitors of the highest capacitance and the lowest capacitance in that range.

---------------------- Page: 13 ----------------------

61048  IEC:2006 – 19 –
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 that of
the maximum capacitance value in the range by 10 % 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 by 10 % or greater.
"Area" denotes total outer surface area of capacitor enclosure ignoring small protrusions,
terminals and fixing studs.
With this procedure the tests qualify all intermediate values of capacitance in the range.
NOTE 1 The "same construction" is that which is declared by the manufacturer to be the same dielectric material,
the same dielectric thickness, the same type of case (metal or plastic), the same generic family of filler
or impregnating liquid, the same type of safety device and the same type of metallization (e.g. zinc or aluminium).
NOTE 2 "Cross-sectional shape" means: round, rectangular, oval, etc.
6 Marking
6.1 Required marking
Capacitors shall be legibly marked as follows:
a) name or trade mark of the manufacturer or responsible vendor;
b) manufacturer's catalogue number and/or model reference;
c) rated capacitance and tolerance;
d) rated voltage;
e) when a discharge resistor is fitted, the symbol ;

f) when a current fuse is fitted, the symbol ;
g) rated frequency or frequency range;
h) rated minimum and maximum temperatures, for example –10 °C/70 °C;
i) if the capacitor is self-healing, the symbol ;

j) if a non-self-healing capacitor is exclusively intended for series operation
the symbol ;

This symbol shall not appear on capacitors bearing the self-healing symbol.
NOTE This type of capacitor is not intended to be connected across the mains supply.
k) type A or B as applicable.
6.2 Additional information
a) Declaration of value of discharge resistor, if fitted.
b) Declaration whether the capacitor does not contain substances which are liquid at
(t + 10) °C.
c

6.3 Durability and legibility of marking
Marking shall be durable and legible.
Compliance is checked by inspection and by trying to remove the marking by rubbing lightly,
for 15 s each, with one piece of cloth soaked with water and another with petroleum spirit.
The marking shall be legible after the test.
NOTE The petroleum spirit used should consist of a solvent hexane with a content of aromatics of maximum
0,1 volume percentage, a kauri-butanol value of 29, an initial boiling point of approximately 65 °C, a dry-point of
approximately 69 °C and a density of approximately 0,68 g/cm³.
7 Terminations
7.1 Terminations shall be provided by means of either cables (tails) or terminals (screw,
screwless, solder tag or the like). Terminations shall be capable of accepting the size and
number of conductors appropriate to the rating and application of the capacitor. Cables (tails)
shall be suitable for the rating of the capacitor, but in no case shall they be smaller than
0,5 mm² and their insulation shall be appropriate to the capacitor rated voltage and
temperatures.
Screw terminals shall comply with section 14 of IEC 60598-1.
Screwless terminals shall comply with section 15 of IEC 60598-1.
7.2 The capacitor case, if of metal, shall either be fitted with an earthing terminal or be
capable of being earthed (or connected to other metal parts, if any, of the luminaire) by
clamping or by an appropriate fixing bracket. The part of the case to which such a clamp is
fitted or the fixing bracket attached shall be free from paint or other non-co
