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 
 
The tested object operated under the operating condition specified in EN61000-3-3:1995/+A1:2001 
The following limits apply  
 
-- “dc” shall not exceed 3.3%. 
-- “dmax” shall not exceed 4/6/7% 
--    d(t)  shall not exceed 3.3% for more than 500ms.

Immunity Test 
 
 
 Performance criteria 
 
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.
