Ball pressure test device
Scope of application:
The ball pressure test device is suitable for evaluating the heat resistance test of electrical enclosures, external parts and plastics made of all insulating materials.
Test Standard:
Ball pressure test device meets IEC884, GB2099, GB4706.1-99, VDE and other test standards.
experiment method:
Place the test piece on the platform in a constant temperature box at 125±2℃, and then press the test piece with the ball end of the device. After testing for 1 hour, take out the test piece and put it in cold water for 10 seconds, and then measure the sag value. The diameter of the steel ball indentation shall not exceed 2mm.
The main parameters:
1. The pressure is 20N
2. Ball pressure radius: r=2.5mm
3. The device is used with aging box
