6.1 Block Diagram of Test Setup
6.2 Test Setup and Test Procedure
Harmonics of the fundamental current were measured up to 40 order harmonics using a digital
power
meter with an analogue output and frequency analyser which was integrated in the harmonic &
flicker
test system. The measurements were carried out under steady conditions .
The appliance has rated input power less than 75W, and is not luminaire, and according to the
standards, no limit apply.

7.2 Test Setup and Test Procedure
7.2.1 Definition
Flicker:
impression of unsteadiness of visual sensation induced by a lighting stimulus whose
luminance or spectral distribution fluctuates with time.
Pst:
Short-term flicker indicator The flicker severity evaluated over a short period (in
minutes); Pst=1 is the conventional threshold of irritability
Plt:
long-term flicker indicator; the flicker severity evaluated over a long period (a few
hous)
Using successive Pst valuse.
dc:
the relative steady-state voltage change
dmax:
the maximum relative voltage change
d(t):
the value during a voltage change
According to EN61000-3-3:1995/+A1:2001, Tests need not be made on equipment which is
unlikely to produce significant voltage fluctuations or flicker.
7.3 Test Protocol

Immunity Test
Performance criteria
The performance criteria are based on the general criteria of the standard and derived from the product
specification
The performance criteria are based on the general criteria of the standard and derived from the product
specification
<or>
Criterion A: Continue to operate as intended during the test. No change of actual operating state, for
example change of channel is allowed as a result of the application of the test. Evaluation is carried out
for audio and video functions.
Evaluation of audio quality:
Unless otherwise specified in this standard, the criterion of compliance with the requirement is a
wanted to unwanted audio signal ratio of >=40dB at a wanted audio signal level of 50mW.
For AM sound receivers the criterion is >=26dB at 50mW.
The criterion for the audio part of TV receivers is >=40dB.
For AM and FM car radios, the criterion is >=26dB at 500mW.
Evaluation of picture quality
The criterion of compliance with the requirement is just perceptible degradation by observation of the
picture, the screen shall be observed under normal viewing conditions(brightness 15~20 Lux), at a
viewing distance of six times the height of the screen.
In the case of video tape equipment the test criteria relate to the picture, assessed on a test-TV-set,
which is connected to the video output terminal of the equipment.
Criterion B: Continue to operate as intended after the test .No degradation of performance or loss of
function. During the test degradation of performance is allowed, however no change of actual operating
state or stored date.
Criterion C: Temporary loss of function is allowed, provided the function is self-recoverable or can be
restored by the operation of the controls.
