1, the ball pressure test apparatus according to GB4706.1-2005, GB2099.1-2008, GB/T5159.21-2006, IEC60695-10-2: 2003 and other standards made. 

 2, the ball pressure test apparatus is provided balls (R2.5mm) and total test force of 20N ± 0.2N ball pressure tester, the pressure level of the state and was placed in a heating chamber of the test surface, the test the specified temperature by 60min +2 min/0min, will test rapid (<10s) immersed in 20 ℃ ± 5 ℃ water cooling 6min 

 ± 2min, 3min removed from the water surface within the measurement of the indentation test diameter, depending on the indentation is more than 2mm in diameter to evaluate the test temperature specified in the 

 Heat deformation.
