60 EMC IMMUNITY REQUIREMENTS
62 FOREWORD
63 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
64 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
65 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
66 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
67 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
68 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
69 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
70 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
71 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
72 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
73 consensus of opinion on the relevant subjects since each technical committee has representation from all
74 interested IEC National Committees.
75 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
76 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
77 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
78 misinterpretation by any end user.
79 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
80 transparently to the maximum extent possible in their national and regional publications. Any divergence between
81 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
82 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
83 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
84 services carried out by independent certification bodies.
85 6) All users should ensure that they have the latest edition of this publication.
86 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
87 members of its technical committees and IEC National Committees for any personal injury, property damage or
88 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
89 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
90 Publications.
91 8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
92 indispensable for the correct application of this publication.
93 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
94 rights. IEC shall not be held responsible for identifying any or all such patent rights.
95 International Standard IEC 61547 has been prepared by IEC technical committee 34: Lamps
96 and related equipment.
97 This fourth edition cancels and replaces the third edition, published in 2020. This edition
98 constitutes a technical revision
99 This edition includes the following significant technical changes with respect to the previous
100 edition:
101 a) The assessment of performance has been split into illuminance performance and control
102 functionality performance
103 b) The test frequency range for radio frequency electromagnetic fields has been increased to
104 6 GHz
105 c) The test level for fast transients for DC power ports has been increased
106 d) New test requirements added for load ports for the injected currents test
107 e) New test requirements added for DC power ports and signal ports for the surge test
IEC CDV 61547 © IEC 2026
108 f) New test requirements added for the voltage dips and voltage short interruption tests for AC
109 power ports

129 EQUIPMENT FOR GENERAL LIGHTING PURPOSES –
130 EMC IMMUNITY REQUIREMENTS
134 1 Scope
135 This part of IEC 61547 which deals with electromagnetic immunity requirements, applies to
136 lighting equipment which is within the scope of IEC technical committee 34, including apparatus
137 such as lamps, luminaires, controlgear for electric light sources, and end-user replaceable
138 modules like non-integrated and semi-integrated LED lamps and LED modules.
139 Lighting equipment with a wireless control function are also within the scope of this document.
140 However, the test is limited to the control of the lighting function only. Radio properties like
141 frequency stability or spurious emissions are not assessed.
142 EXAMPLE Colour/light level control via a wireless interface are meant to stay intact during and after an immunity
143 test.
144 Also included in the scope of this document is lighting equipment that interfaces with systems
145 or installations other than common power supply networks.
146 Excluded from the scope of this document are:
147 – components or modules designed to be integrated into lighting equipment but not intended
148 for end-user replacement.
149 – equipment for which the electromagnetic compatibility requirements in the radio -frequency
150 range are explicitly formulated in other product immunity standards, even if they incorporate
151 a built-in lighting function.
152 NOTE 1 Examples of exclusions are:
153 – equipment with built-in lighting devices for display back lighting, scale illumination and signaling;
154 – SSL-displays;
155 – range hoods, refrigerators, freezers;
156 – photocopiers, projectors;
157 – electronic switches for fixed installations;
158 – lighting equipment for road vehicles (within the scope of CISPR 12);
159 – lighting equipment for aircraft and airfield facilities.
160 NOTE 2 Modules that are not end-user replaceable are not in the scope of this document but can be tested according
161 to this document for information purposes (for instance, of luminaire manufacturers).
162 In multi-function equipment where the lighting function operates independently from other
163 functions, the electromagnetic immunity requirements of this document apply to the lighting
164 function only.
165 The requirements of this document are based on the generic immunity standard for residential,
166 commercial and light-industrial environments IEC 61000-6-1:2016, but modified to lighting
167 engineering practice.
168 It can be expected that lighting equipment complying with the requirements of this document
169 will operate satisfactorily in other environments. In some special cases, measures can be taken
170 to provide higher immunity. In this document it is impracticable to deal with all these possibilities.
171 Such requirements can be established by contractual agreement between supplier and
172 purchaser.

310 4 Performance criteria
311 4.1 General
312 For the various immunity tests that apply, the performance criteria are specified in 4.2. The
313 following functions shall be assessed with consideration of the instructions for use.
314 – the illuminance of the Iuminaire or of the light source(s);
315 – the control function, for example switching on and off, light level setting, colour adjustment,
316 wireless control.
317 The functions assessed and the performance criteria for each individual test shall be noted in
318 the test report.
319 4.2 Categorization of performance criteria
320 The following three categories of performance criteria apply.
321 a) Performance criterion A
322 During the test, no visible change of the illuminance according to 4.3.1 shall be observed
323 and the control function (see 4.3.2), if any, shall operate during the test as intended. The
324 EUT shall operate as intended after the test.
325 b) Performance criterion B
326 During the test, the illuminance can change to any value. After the test, the illuminance shall
327 be restored to its initial value (see 4.3.1) within 1 minute (30 minutes for high pressure gas
328 discharge lamps). Control function need not operate during the test, but after the test, the
329 mode of the control shall be the same as before the test, provided that during the test no
330 mode changing commands were given.
331 NOTE 1 High pressure discharge lamps by their technical nature require up to 30 min to fully restore
332 the previous illuminance.
IEC CDV 61547 © IEC 2026
333 NOTE 2 In safety critical applications, for example emergency escape lighting, according to the
334 applicable standards much shorter restoration times can be required.
335 c) Performance criterion C
336 During and after the test, any change of the illuminance is allowed and the light source(s)
337 can extinguish. After the test, within 30 min, all functions shall return to normal, if necessary
338 by temporary interruption of the mains supply or operating the control function.
339 NOTE For circuit protections recovery up to 30 min can be required.
340 .
341 The application of the different performance criteria for the various types of tests and for
342 different lighting equipment are specified in Clause 6.
343 4.3 Assessment of performance
344 4.3.1 Assessment of illuminance performance
345 According to clause 4.2, the illuminance variation is checked during and after the test for
346 performance criterion A, and after the test for performance criterion B. A change of illuminance
347 shall be checked  by measurement. Absolute measurement is not required, relative
348 measurements can be performed. Other photometric quanti
