Appliance:

The ball pressure is a specified testing machine designed in compliance with standards for ball Pressure test to 

test heat resistance of nonmetallic material.  It is ideal for heat resistance tests in electrical equipment and components, non-ceramic solid electrical insulating materials, etc.

Technical parameters：

1. load: 20N±0.2N

2. material: 304 stainless steel

3. steel ball: bearing steel R2.5mm    ISO 3290

4. foothold: 50×100  2.5×25mm

5. standards: IEC60335,IEC60695

(This ball pressure tester suits for high temperature box)

how to test?

the ball pressure test is put specified Ball (R2.5mm) and total test force 20N ± 0.2N on the ball pressure tester which is in the form of horizontal state and placed on the sample surface in heating tank. in specified temperature , after 60min + 2min / 0min, then quickly put the sample (<10s)  in the 20 ℃ ± 5 ℃ water for cooling 6min ± 2min. After taking from water, measure sample surface indentation diameter within 3 min. depending on whether the indentation diameter is more than 2mm to assess the ability of the test heat distortion under the temperature prescribed.
