Lamp controlgear - Part 2-12: Particular requirements for d.c. or a.c. supplied electronic ballasts for discharge lamps (excluding fluorescent lamps)

IEC 61347-2-12:2005+A1:2010 specifies particular general and safety requirements for d.c. or a.c. supplied electronic ballasts. The supply comprises a.c. voltages up to 1000 V at 50 Hz/60 Hz. The type of ballast is an convertor that may contain igniting and stabilising elements for operation of a discharge lamp at d.c. or at a frequency that can deviate from the supply frequency. The lamps associated with the ballast are specified in IEC 60188 (High pressure mercury vapour lamps), IEC 60192 (Low pressure sodium vapour lamps), IEC 60662 (High pressure sodium vapour lamps), IEC 61167 (Metal halide lamps) and else for general purpose lighting. Ballasts for fluorescent lamps and for lamps for special applications like for theatre and for vehicles are excluded. The technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. A vertical line in the margin shows where the base publication has been modified by amendment 1. Additions and deletions are displayed in red, with deletions being struck through. This consolidated version consists of the first edition (2005) and its amendment 1 (2010). Therefore, no need to order amendment in addition to this publication.
This publication is to be read in conjunction with IEC 61347-1:2000.

Appareillages de lampes - Partie 2-12: Exigences particulières pour les ballasts électroniques alimentés en courant continu ou alternatif pour lampes à décharge (à l'exclusion des lampes fluorescentes)

La CEI 61347-2-12:2005+A1:2010 spécifie les exigences particulières et les exigences de sécurité pour les ballasts électroniques alimentés en courant continu ou alternatif. L'alimentation comprend les tensions alternatives jusqu'à 1 000 V, de fréquence égale à 50 Hz ou 60 Hz. Le type de ballast est un inverseur qui peut inclure des moyens d'amorçage et de stabilisation pour le fonctionnement d'une lampe à décharge en courant continu ou à une fréquence qui peut différer de la fréquence du réseau d'alimentation. Les lampes associées avec le ballast sont spécifiées dans la CEI 60188 (Lampes à vapeur de mercure à haute pression), la CEI 60192 (Lampes à vapeur de sodium à basse pression), la CEI 60662 (Lampes à vapeur de sodium à haute pression), la CEI 61167 (Lampes aux halogénures métalliques), et autres pour l'éclairage général. Les ballasts pour les lampes fluorescentes et pour les lampes destinées à des applications spéciales comme pour le théâtre et les véhicules sont exclus. Le contenu technique de cette version consolidée est donc identique à celui de l'édition de base et à son amendement; cette version a été préparée par commodité pour l'utilisateur. Une ligne verticale dans la marge indique où la publication de base a été modifiée par l'amendement 1. Les ajouts et les suppressions apparaissent en rouge, les suppressions sont barrées.  Cette version consolidée comprend la première édition (2005) et son amendement 1 (2010). Il n'est donc pas nécessaire de commander l'amendement avec cette publication.
Cette publication doit être lue conjointement avec la CEI 61347-1:2000.

Part 2-12: Particular requirements for d.c. or a.c. supplied electronic
ballasts for discharge lamps (excluding fluorescent lamps)



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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 consolidated version of IEC 61347-2-12 consists of the first edition (2005)
[documents 34C/683/FDIS and 34C/687/RVD] and its amendment 1 (2010) [documents
34C/898/CDV and 34C/933/RVC]. It bears the edition number 1.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

INTRODUCTION
This standard, and the parts which make up IEC 61347-1, in referring to any of the clauses of
IEC 61347-1 specify the extent to which such a clause is applicable and the order in which the
tests are to be performed; they also include additional requirements as necessary. All parts
which make up IEC 61347-2 are self-contained and therefore do not include references to
each other.
Where the requirements of any of the clauses of IEC 61347-1 are referred to in this standard
by the phrase “The requirements of Clause n of IEC 61347-1 apply, this phrase is interpreted
as meaning that all requirements of the clause in question of Part 1 apply, except any which
are clearly inapplicable to the specific type of lamp controlgear covered by this particular part
of IEC 61347-2.

16 Ignition voltage
16.1 Instruments
Measurements are made by oscilloscope or electrostatic voltmeters for ignition voltages up to
100 kV.
NOTE A typical electrostatic voltmeter is prescribed in Figure 1 of IEC 61347-2-1.
Many electronic ballasts cannot have grounded outputs. In case a differential probe has to be used, it may have an
impedance greater than 1 MΩ at up to 10 kHz. For higher frequencies f the probe must have an impedance Z
greater than a 15 pF capacitor (C) based on the equation
Z = 1/(2π f C)
The cut-off frequency should be ≥30 MHz at –3dB.

---------------------- Page: 12 ----------------------
61347-2-12 Ó IEC:2005+A1:2010 – 11 –
Above 15 kV a spherical spark gap can be used, using the procedure based on that given in
IEC 60052, and taking note of Annex I.
In case of doubt, the measurement with the electrostatic voltmeter shall be the reference
method.
16.2 Ignition voltage limits
The maximum value of the ignition voltage shall not exceed 5 kV when operated at the rated
voltage and with a load capacitance of 20 pF (including the capacitance of the probe), or
using the circuit shown in Figure 1 of IEC 61347-2-1 for either positive or negative pulses,
taking into account however, the maximum ignition voltage specified in the relevant lamp data
sheets.
If not otherwise stated on the relevant lamp data sheets, for electronic ballasts with ignition
voltages over 5 kV, the maximum value shall not exceed 1,3 x U declared by the
p
manufacturer when operated at the rated supply voltage and with a load capacitance of 20 pF.
NOTE In some countries, the ignition voltage is restricted to 4 kV.
16.3 Ignition time cut-out
Electronic ballasts equipped with cut-outs shall be of such a construction that, in the case of
non-igniting lamps, the cut-out interrupts at least the production of the ignition voltage.
After the cut-out has interrupted the circuit, the generation of the ignition voltage is allowed
either after disconnecting and reconnecting the ballast to the supply or by control signal.
Electronic ballasts with ignition voltages over 5 kV shall be provided with a cut-out for igniting.
Time to cut-out is limited:
– for ignition voltages 5 to 10 kV to 60 s,
– for ignition voltages > 10 kV a) to 3 s, or
 b) to 30 s, if declared in the manufacturer’s literature.
The cut-out time of 60 s for ignition voltage from 5 kV to 10 kV can be extended, depending
on the lamp type, up to a period of 20 min within which the combined intervals of ignition
attempts add up to 60 s, provided it is evident for the maintenance service staff that the
controlgear is still trying to ignite.
17 Abnormal conditions
The ballast shall not impair safety when operated under abnormal conditions at any voltage
between 90 % and 110 % of rated supply voltage. The range of rated supply voltage may be
declared differently by the manufacturer.
Compliance is checked by the following test.
Each of the following conditions shall be applied with the ballast operating to the
manufacturer’s instructions (including a heat sink, if specified) for 1 h:
