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 express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are 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.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61000-4-15 has been prepared by subcommittee 77A: Low-
frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
It forms section 15 of part 4 of the IEC 61000 series. It has the status of a basic EMC
publication in accordance with IEC guide 107.
The text of this standard is based on the following documents:
FDIS Report on voting
77A/180/FDIS 77A/190/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.
Annex A forms an integral part of this standard.

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 4: Testing and measurement techniques –
Section 15: Flickermeter – Functional and
design specifications
1 Scope and object
This section of IEC 61000-4 gives a functional and design specification for flicker measuring
apparatus intended to indicate the correct flicker perception level for all practical voltage
fluctuation waveforms. Information is presented to enable such an instrument to be
constructed. A method is given for the evaluation of flicker severity on the basis of the output of
flickermeters complying with this standard.
This section is based on specifications prepared by the “Disturbances” working group of the
International Union for Electroheat (UIE) and published in 1992. Consequently the flickermeter
specifications in this section relate only to measurements of 230 V, 50 Hz inputs; specifications
for other voltages and other frequencies are under consideration.
The object of this section is to provide basic information for the design and the instrumentation
of an analogue or digital flicker measuring apparatus. It does not give tolerance limit values of
flicker severity.
