Ball pressure test apparatus

The ball pressure test apparatus is designed according to IEC60695-10-2, IEC60335, IEC60601, GB4706.1 and etc. the surface of the part to be tested is placed in the horizontal position and a steel ball of 5 mm diameter is pressed against the surface with a force of 20 N. The test is performed in a heating cabinet at a temperature of 75°C ± 2°C. The ball is withdrawn after 1 h and the diameter of the impression made by the ball is measured. An impression greater than 2 mm in diameter constitutes a failure.

1. Ball diameter: 5mm (R2.5mm)

2. Test Pressure: 20N±0.2N

3. Material: Stainless Steel

4. Sample supportor: Φ50mm-length 100mm, cylinder sharp
