The ball pressure test device is designed according to the requirements of "ball pressure test" stipulated in GB2099 and other standards. It is mainly used for heat resistance testing of household and similar plug and socket products. It is used by relevant manufacturers and quality inspection departments to conduct product quality testing. and control equipment required
The ball pressure test is to press a steel ball (R2.5mm) and a ball pressure Tester with a total test of 20N±0.2N on the surface of the test sample in a horizontal state and placed in the heating box, and test it at the specified temperature of the test sample. After 60min + 2min/0min, quickly (<10s) immerse the sample into 20℃ ± 5℃ water and cool for 6 minutes. Measure the diameter of the indentation on the surface of the sample within 3 minutes of taking it out of the water. Evaluate the sample based on whether the indentation diameter exceeds 2mm. Thermal deformation resistance at the specified temperature.
1. According to the test requirements, first place the ball pressure test device in the heating box for a long enough time to ensure that the ball pressure test device has reached a stable test temperature before the test starts.
2. Place the component under test on the support base so that it is in direct contact with the support base.
3. Place the surface of the component under test in a horizontal position and press the steel ball against the surface. The test should be conducted in a heating box at a temperature specified by the standard.
4. After the test reaches the time specified in the standard, remove the ball from the sample, and after cooling according to the requirements specified in the standard, measure the diameter of the indentation of the steel ball to determine whether it is qualified.
