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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
This part of IEC 61347, and the parts which make up IEC 61347-2, 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.
The technical requirements in this document compared to IEC 61347-2-10:2000 and
IEC 61347-2-10:2000/AMD1:2008 are essentially unchanged. Nevertheless, a new edition of
this document could not be avoided, as without the introduction of dated references to
IEC 61347-1:2015 and IEC 61347-1:2015/AMD1:2017, the fourth edition of IEC 61347-1:—
would have been implicitly applicable due to the undated nature of the references to
IEC 61347-1 in IEC 61347-2-10:2000 and IEC 61347-2-10:2000/AMD1:2008.
This document, in referring to any of the clauses of IEC 61347-1:2015 and
IEC 61347-1:2015/AMD1:2017, specifies the extent to which such a clause is applicable.
Additional requirements are also included, as necessary.
In order to check the safety of controlgear, it is necessary to check their performance. However,
since no standardization of the characteristics of neon tubes exists, reference loads are
specified in this document to ensure reproducible test results.

LAMP CONTROLGEAR –
CONTROLGEAR FOR ELECTRIC LIGHT SOURCES – SAFETY –
Part 2-10: Particular requirements for electronic invertors
and convertors for high-frequency operation of cold start
tubulardischarge lamps (neon tubes)
Particular requirements – Electronic controlgear for high-frequency
operation of tubular cold-cathode discharge lamps (neon tubes)
1 Scope
This part of IEC 61347 specifies particular safety requirements for electronic invertors and
convertors controlgear for high-frequency operation of tubular cold-cathode discharge lamps
used in signs and luminous discharge tube installations and operating with an output voltage
exceeding 1 000 V but not exceeding 10 000 V for direct connection to DC or AC supply
voltages not exceeding 1 000 V (at 50 Hz or 60 Hz or 1 000 V d.c in case of alternating current).
NOTE 1 Historically, such types of controlgear were referred to as invertors or convertors.
NOTE 12 In Japan, the output voltage limit for the application of this document is set to 15 000 V is acceptable.
The requirements for two types of invertors and convertors, types A and B, are specified as
follows:
– Type A unit: an invertor or convertor operating within the frequency range 20 kHz to 50 kHz,
and having an output voltage (between terminals) not exceeding 5 000 V peak, a maximum
output current limited to 35 mA (r.m.s.) and 50 mA (peak value). The supply voltage does
not exceed 250 V at 50 Hz or 60 Hz or 250 V d.c.
NOTE 2 The output current of a type A unit may be considered as not presenting an electric shock hazard due to
the limits on the current and frequency range.
NOTE 3 In Japan, the output voltage of 15 000 V is acceptable.
– Type B unit: an invertor or convertor having a no-load output voltage not exceeding 5 000 V
to earth or 10 000 V between terminals, operating within the frequency range 10 kHz to
100 kHz with a maximum output current limited to 200 mA (r.m.s.) and 400 mA (peak value).
NOTE 4 Type B units require additional protection in the output circuit.
NOTE 5 In Japan, a type B unit exceeding 50 mA and/or the secondary grounded is not acceptable.
In order to check the safety of invertors or convertors, it is necessary to check their
performance. However, since no standardization of the characteristics of neon tubes exists,
reference loads are specified in this standard to ensure reproducible test results.
The rated maximum operating temperature of the winding, t , is not applicable to this standard.
w
This document applies for controlgear of type A and controlgear of type B, which are specified
as follows:
– Type A: controlgear operating within the frequency range 20 kHz to 50 kHz, and having an
output voltage not exceeding 5 000 V peak between terminals, with a maximum output
current limited to 35 mA (RMS) and 50 mA (peak value) and a supply voltage not exceeding
250 V.
NOTE 3 The output current of a type A unit can be considered as not presenting an electric shock hazard due
to the limits on the current and frequency range.
NOTE 4 In Japan, the output voltage of 15 000 V is acceptable.
– Type B: controlgear operating within the frequency range 10 kHz to 100 kHz and having a
no-load output voltage not exceeding 10 000 V between terminals or not exceeding 5 000 V
to earth, with a maximum output current limited to 200 mA (RMS) and 400 mA (peak value).
NOTE 5 In Japan, a type B controlgear providing an output current exceeding 50 mA is not acceptable.

Part 2-10: Particular requirements –
Electronic controlgear for high-frequency operation of tubular
cold-cathode discharge lamps (neon tubes)
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC

INTRODUCTION
The technical requirements in this document compared to IEC 61347-2-10:2000 and
IEC 61347-2-10:2000/AMD1:2008 are essentially unchanged. Nevertheless, a new edition of
this document could not be avoided, as without the introduction of dated references to
IEC 61347-1:2015 and IEC 61347-1:2015/AMD1:2017, the fourth edition of IEC 61347-1:—
would have been implicitly applicable due to the undated nature of the references to
IEC 61347-1 in IEC 61347-2-10:2000 and IEC 61347-2-10:2000/AMD1:2008.
This document, in referring to any of the clauses of IEC 61347-1:2015 and
IEC 61347-1:2015/AMD1:2017, specifies the extent to which such a clause is applicable.
Additional requirements are also included, as necessary.
In order to check the safety of controlgear, it is necessary to check their performance. However,
since no standardization of the characteristics of neon tubes exists, reference loads are
specified in this document to ensure reproducible test results.

CONTROLGEAR FOR ELECTRIC LIGHT SOURCES – SAFETY –
Part 2-10: Particular requirements –
Electronic controlgear for high-frequency operation of tubular
cold-cathode discharge lamps (neon tubes)
1 Scope
This part of IEC 61347 specifies safety requirements for electronic controlgear for high-
frequency operation of tubular cold-cathode discharge lamps used in signs and luminous
discharge tube installations and operating with an output voltage exceeding 1 000 V but not
exceeding 10 000 V for direct connection to DC or AC supply voltages not exceeding 1 000 V
(at 50 Hz or 60 Hz in case of alternating current).
NOTE 1 Historically, such types of controlgear were referred to as invertors or convertors.
NOTE 2 In Japan, the voltage limit for the application of this document is set to 15 000 V.
This document applies for controlgear of type A and controlgear of type B, which are specified
as follows:
– Type A: controlgear operating within the frequency range 20 kHz to 50 kHz, and having an
output voltage not exceeding 5 000 V peak between terminals, with a maximum output
current limited to 35 mA (RMS) and 50 mA (peak value) and a supply voltage not exceeding
250 V.
NOTE 3 The output current of a type A unit can be considered as not presenting an electric shock hazard due
to the limits on the current and frequency range.
NOTE 4 In Japan, the output voltage of 15 000 V is acceptable.
– Type B: controlgear operating within the frequency range 10 kHz to 100 kHz and having a
