foreign matter such as staplers or clips.  
 
6.2.2  Preheating time test  
Turn on the heating switch of the machine and be gin timing until the working 
temperature reaches its set value (the working indicator lights) ; this time should be 10min. 
the test should be repeated 3 times.  
 
6.2.3  Laminating effect test  
The laminating effect test should be conducted as follows:  
a) Whe n the machine has reached its set temperature (the working indicator lights) , the 
machine should be in its normal working state and a card protecting film and a piece of 
A4 paper should then be passed through the laminator.  
b) Take the laminated sample, c ut two diagonal lines on the top rubber surface of the 
sample with an art knife and tear the cut surface at 4 different angles. The visual check 
must meet the requirements of 5.2.2 b).  
 
6.2.4  Continuous working time test  
Having reached its set working temp erature (the working indicator lights), the machine 
is in its normal working state. At this time, prepare 10 card protecting films and 10 pieces of 
A4 paper and laminate these continuously and alternately with a film and a piece of paper 
until the continuo us sealing time exceed s the rated continuous working time. Then , 
laminate another card protecting film and a piece of A4 paper ; the laminated product 
should meet the requirements of 5.2.2.  
 
6.2.5  Maximum laminating thickness test  
Having reached its set wor king temperature (the working indicator lights), the machine 
is in its normal working state. At this time, laminate a card protecting film and a piece of A4 
paper with the laminated thickness exceeding 95% of the rated maximum thickness. Under 
these condit ions, the laminator should be able to operate normally and the laminated 
product should meet the requirements of 5.2.2.  
 
6.2.6  Laminating speed test  
Pass a card protecting film holding a piece of A4 paper through the laminator and 
count the time taken, beginning at the time when the film enters the machine until the end 
of the film leaves the machine , and then calculate the laminating speed by dividing the GB ×××× —×××× 
length (mm) of the film by the time (min) taken . Repeat 10 times and take the mean value 
as the lamin ating speed.   
 
6.3 Noise test  
 
6.3.1  Test conditions  
The noise test should be conducted under the following conditions:  
a) The laminator should be placed on a stable bench, on which a n elastic cushion with 
a thickness of 5 -10mm is spread;

c) The noise test should be conducted in a semi -anechoic room. If the test is 
conducted in another environment, it should conform to the stipulations of GB/T4214.1;  
d) After the laminator has operated  for 3 min with a 80µm PET+EVA card protecting 
film at a thickness ratio of 1:1 and a piece of paper of 70g/m2A4 in accord ance  with 
QB/T 2342 -2006, the noise should be tested as shown in Fig 1.   
 
The coordinate s of the test points in the figure are listed  in Table 1.

Note: The front of the laminator faces toward the X axis. Test  distance is 1m.  
Place the microphone successively at point s 1, 2, 3 and 4, detect the noise with a sound 
level meter (A -weighted) and read the arithmetic mean value of the noise at the 4 points 
when the noise is at its peak as the mean sound press ure level of noise of the machine.   
 
6.3.2  Calculation formula  
The sound power level of noise is calculated as per formula (1):  
 
 
Where:   (1) 
 
Lw - Sound  power value of the laminator (dB);  
 
 
Lp - Mean sound pressure level of noise at 4 test points (dB); 
 
S - Envelope area of the measurement surface (m2), assuming 11, 12, 13 
respectively as the length, width and height of the laminator box (m) ; 
 
 
 
 
 
Then, S = 4  (ab+bc+ac)  
S0 - Area of base level, S0= 1m2
