INTERNATIONAL ELECTROTECHNICAL COMMISSION
EQUIPMENT FOR GENERAL LIGHTING PURPOSES -
EMC IMMUNITY REQUIREMENTS
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 co-operation on all questions concerning standardization in the electrical and electronic
fields. To this end and in addition to other activities, the IEC publishes International Standards. 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, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3) They have the form of recommendations for international use published in the 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 latter.
International Standard IEC 1547 has been prepared by IEC technical committee 34: Lamps and
related equipment.
The text of this standard is based on the following documents:
DIS Report on voting
34/39/DIS 34/40/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.

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-in other equipment such as:
• scale illumination or indicators;
• photocopiers;
• slide and overhead projectors;
• video display units.
However, in multi-function equipment where the lighting part operates independently from
other parts, the lighting part shall comply with the requirements of this standard.
The requirements of this standard are based on the requirements for domestic, commercial and
light-industrial environments as given in the future IEC 1000-6-1 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 greater immunity. It is impracticable to deal with all these possibilities. Such
requirements may be established by contractual agreement between supplier and purchaser.
This standard shall be read in conjunction with the relevant basic and/or product standard(s).
2 Normative references

3 Definitions
For the purpose of this International Standard, the definitions of IEC 50(161) and IEC 50(845)
apply, together with the following definitions:
3.1 port: Particular electrical interface of the specified equipment with the external
electromagnetic environment.
3.2 enclosure port:
The physical boundary of the equipment through which electromagnetic
fields may radiate or penetrate.
Enclosure port
AC power port
Earth port

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 luminaire or of the lamp(s);
— the functioning of the control in case of equipment which includes a regulating
control or concerns the regulating control itself;
— the functioning of the starting device, if any.
1547 ©IEC:1995 — 11 —
4.2 The following performance criteria apply to lighting equipment:
Performance criterion A:
During the test no change of the luminous intensity shall be observed and the regulating
control, if any, shall operate during the test as intended.
Performance criterion B:
During the test the luminous intensity may change to any value. After the test the luminous
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.
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
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 that the ambient light level does not influence the measuring result.
Precautions to achieve reproducible results given in the relevant lamp performance standards
shall be observed.
4.4 Effects of electromagnetic phenomena as described in this standard on the life of the light
sources, are excluded from this standard.
5 Test specifications
5.1 General
Immunity requirements for equipment defined in the scope concern:
—
electrostatic discharges;
— continuous and transient disturbances;
—
radiated and conducted disturbances;
— radio frequency and 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.
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.
1547 ©IEC:1995 — 13 —
It may be determined from consideration of the electrical characteristics and usage of a
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 1000-4-2, 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 1000-4-2.
NOTE — "accessible" means accessible under normal operating conditions including user maintenance.
