EMC IMMUNITY REQUIREMENTS





INTERPRETATION SHEET 1


This interpretation sheet has been prepared by IEC technical committee 34: Lamps and
related equipment.


The text of this interpretation sheet is based on the following documents:
ISH Report on voting
34/180/ISH 34/185/RVD

Full information on the voting for the approval of this interpretation sheet can be found in the
report on voting indicated in the above table.
___________
The draft is based on the outcome of documents 34/155/DC and 34/158/INF.
Introduction:
Test conditions of dimmable lighting equipment are unclear in IEC 61547 for dimmable
lighting equipment with dim level other than 50 % ± 10 %. Some HID control units have only
one dim level, for example 65 %.
Present text, Clause 7, second paragraph, first sentence:
“Equipment including a regulating control shall be tested at a light output level of 50 %
± 10 %.”
Interpretation for equipment which could not fulfill the test dim level conditions:
If a light output level of 50 % ± 10 % is not available for equipment including regulating
control, the test shall be done at the level which is closest to 50 %. If two steps equally distant
to 50 % are available, the lower level (< 50 %) shall be used for the test.

EMC IMMUNITY 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 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.
International Standard IEC 61547 has been prepared by IEC technical committee 34: Lamps

and related equipment.
This second edition cancels and replaces the first edition, published in 1995, and its
Amendment 1 (2000). It constitutes a technical revision
The main reason for this revision is to update the dates of the references to the basic
standards which also required some editorial changes in the tables. Other changes are:
1 Scope: clearly excludes multimedia equipment with lamps (e.g. TV);
3.2 Enclosure port: removal of the ”earth port” in Figure 1 as in the generic EMC
standards; the note below Figure 1 in the first edition relates to a requirement and
moved to the main text under 5.1 General;
5.6 Injected currents: update of the names of the example CDN’s;
5.7 Surges: test only at the peak of the mains voltage by deleting the requirement to test
at zero crossings;

---------------------- Page: 7 ----------------------
61547 © IEC:2009 – 5 –


5.8 Voltage dips and interruptions: clarifying that the voltage level changes at the zero

crossing;

6.3.2 Independent auxiliaries: Table 14 has been simplified because most independent

auxiliaries have identical performance criteria;


6.3.3 Luminaires: Table 15 has been simplified because most luminaires have identical
performance criteria; correcting the error in the injected current column by changing

the B into A for luminaires with electronic ballast for discharge lamps; additionally, the

requirements for emergency luminaires operating in high risk task areas are updated

to meet the levels specified in IEC 60598-2-22;

7 Conditions during testing: the ”under consideration” for the operating conditions for
starting devices has been deleted; the supply voltage and frequency during the test

are clearly stated; shortening the immunity test for equipment incorporating a
regulating control by testing at one light output level (50 % ± 10 %) instead of testing
at three light output levels which are difficult to adjust and do not provide extra
protection.
The text of this standard is based on the following documents:
FDIS Report on voting
34/127/FDIS 34/130/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This standard is to be read in conjunction with the relevant basic and/or product standard(s).
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
The contents of the corrigendum of April 2010 and Interpretation sheet 1 of June 2013 have
been included in this copy.

EQUIPMENT FOR GENERAL LIGHTING PURPOSES –

EMC IMMUNITY REQUIREMENTS







1 Scope


This International Standard for electromagnetic immunity requirements applies to lighting
equipment which is within the scope of IEC technical committee 34, such as lamps, auxiliaries
and luminaires, intended either for connecting to a low voltage electricity supply or for battery

operation.
Excluded from the scope of this standard is equipment for which the immunity requirements
are formulated in other IEC or CISPR standards such as:
– lighting equipment for use in transport vehicles;
– entertainment lighting control equipment for professional purposes;
– lighting devices built into other equipment such as:
• scale illumination or indicators;
• photocopiers;
• slide and overhead projectors;
• multimedia equipment.
However, in multi-function equipment where the lighting part operates independently from
other parts, the electromagnetic immunity requirements of this standard apply to the lighting
part.
The requirements of this standard are based on the requirements for domestic, commercial
and light-industrial environments as given in IEC 61000-6-1, but modified to lighting
engineering practice.
It can be expected that lighting equipment complying with the requirements of this standard
will operate satisfactorily in other environments. In some special cases, measures have to be
taken to provide higher immunity. It is impracticable to deal with all these possibilities. Such
requirements may be established by contractual agreement between supplier and purchaser.

4 Performance criteria
4.1 A functional description of performance criteria, during or as a consequence of the
immunity testing, shall be provided by the manufacturer and noted in the test report.
The performance of lighting equipment shall be assessed by monitoring:
– the luminous intensity of the Iuminaire or of the lamp(s);
– the functioning of the control in the case of equipment which includes a regulating control
or concerns the regulating control itself;
– the functioning of the starting device, if any.
4.2 The performance criteria given hereafter apply to lighting equipment.
a) Performance criterion A
During the test, no change of the Iuminous intensity shall be observed and the regulating
control, if any, shall operate during the test as intended.
b) Performance criterion B
During the test, the Iuminous intensity may change to any value. After the test, the Iuminous
intensity shall be restored to its initial value within 1 min. Regulating controls need not
function during the test, but after the test, the mode of the control shall be the same as before
the test provided that during the test no mode changing commands were given.

c) Performance criterion C
During and after the test, any change of the luminous intensity is allowed and the lamp(s) may
be extinguished. After the test, within 30 min, all functions shall return to normal, if necessary
by temporary interruption of the mains supply and/or operating the regulating control.
Additional requirement for lighting equipment incorporating a starting device: After the test,
the lighting equipment is switched off. After half an hour, it is switched on again. The lighting
equipment shall start and operate as intended.
4.3 A change of luminous intensity may be checked by visual observation but, in case of
doubt, the following applies.
The luminous intensity of a luminaire or of the lamp(s) shall be measured by means of a
illuminance (lux) meter which is positioned in an axis perpendicular to the main plane of the

---------------------- Page: 11 ----------------------
61547 © IEC:2009 – 9 –


luminaire or lamp(s), in its centre and at a distance for proper operation of the lux meter. The

luminous intensity shall be deemed to be unchanged if the measured intensities do not

deviate by more than 15 %.


Care shall be taken to ensure the ambient light level does not influence the measurement

results.


Precautions to achieve reproducible results given in the relevant lamp performance standards

shall be observed.


4.4 The effects of electromagnetic phenomena (as described in this standard) upon the life

of the equipment under test are excluded from this standard.
5 Test specifications
5.1 General
Immunity requirements for equipment defined within the scope concern:
– electrostatic discharges;
– continuous and transient disturbances;
– radiated and conducted disturbances;
– mains supply-related disturbances.
They are given in Subclauses 5.2 to 5.9 on a port by port basis.
Tests are applied to the relevant ports of the equipment as indicated in the respective
subclauses. For the purposes of this standard, d.c. power ports for supplying regulating
controls are considered to be signal ports. Tests shall be conducted in a well-defined and
reproducible manner. Tests shall be carried out as single tests in sequence. The sequence of
testing is optional.
It may be determined from consideration of the electrical characteristics and usage of
particular equipment that some of the tests are inappropriate and therefore unnecessary. In
such cases it is required that the decision not to test be recorded in the test report.
The description of the test, the test generator, the test methods and the test set-up are given
in the basic standards, which are referred to in the relevant subclauses.
Test levels are generally based on level 2 values as recommended in the basic standards.

5.2 Electrostatic discharges
These tests are carried out according to IEC 61000-4-2, with test levels as given in Table 1 of
this standard. Contact discharge is the preferred test method. Twenty discharges (10 with
positive and 10 with negative polarity) shall be applied on each accessible metallic part of the
enclosure (terminals are excluded). Air discharges shall be used where contact discharges
cannot be applied. Discharges shall be applied on the horizontal or vertical coupling planes,
as specified in IEC 61000-4-2.
NOTE "Accessible" means accessible under normal operating conditions including user maintenance.
