Requirements for the CE mark
Harmonics and flicker test
(pages 2-4)
The ZES ZIMMER compliance test system CE-Test61k allows
to test products interferences towards the power distribu-
tion system caused by current harmonics in accordance
with EN 61000-3-2/-12 and flicker in accordance with
EN 61000-3-3/-11 (directive 2004/108/EU).
Additionally it is possible to measure and document pertur-
bations of the public power system in the frequency range
from 2 kHz to 9 kHz according to EN 61000-4-7 annex B.
CE-compliance test system for
current harmonics and flicker
Stand-by power compliance test
(pages 6-7)
The ZES ZIMMER CE-Test-Standby system offers monitoring
the power consumption in standby mode of home appli-
ances, IT devices and similar equipment. The system tests
conformity with the requirements of the EU directive on
ecodesign 2009/125/EU, in conjunction with regulation
1275/2008 and in accordance with IEC/EN 62301. The dif-
ferent components of the system – the precision power mea-
surement devices
LMG95 and LMG500, current and voltage
sensors as well as power sources – can easily be integrated
into other test systems such as dedicated efficiency or con-
sumption measurement in more general operations.
Standards concerning the electromagnetic compatibility of
a product classify the permissible degree of electromag-
netic interference emission as well as immunity to it. Two
different types of electromagnetic interference emissions
that affect the public power system are considered: current
harmonics and flicker.
Even with a purely sinusoidal voltage, an electrical device
with a non-linear load characteristic creates current harmon-
ics. Through the impedance of the mains, these harmonics
cause voltage drops and distort the line voltage. These
device generated harmonics are therefore the cause for a
reduced line voltage and quality of the AC power network.
In addition to that, certain devices such as stoves, instant
water heaters, etc. operate by switching the power repeatedly
on and off. These sudden load changes result in line voltage
variations perceived as fluctuations in the brightness of elec-
tric illumination, technically-called flicker. This is as well an
undesired perturbation of the power network quality.
Measuring methods and limits for these low-frequency per-
turbations on the mains caused by current harmonics and
flicker are specified in various standards. A product may
only bear the CE mark if conformity to these standards has
been verified and documented.
The standards distinguish between frequency ranges and
current ranges. The standards EN 61000-3-2 and -12 apply
to current harmonics up to the 40th order. The compliance
test regarding flicker is specified in the standards 61000-3-3
and -11 (see adjacent table). For example, standard EN
61000-3-2 for devices of a nominal current up to 16 A
defines the measuring and evaluation methods as well as
the limits for permissible current harmonics in the fre-
quency range up to 2 (2.4) kHz. There are 4 different classes
(A, B, C, and D) for equipment under test that have different
limit values for current harmonics.

Electrical installations, systems and devices which are to be marketed within the European Union (EU) must comply with the
European Union directives and regulations. The manufacturer resp. the importer is obliged to verify and mandatorily declare
this with the CE mark.
Amongst others, directives concerning electromagnetic compatibility and environmentally suitable designs of energy-using
products (e.g. the European Directive 2009/125/EC on ecodesign) have to be adhered and implemented.
