Ball pressure tester, ball pressure heat resistance testing device

1、 Compliant with standards:This device meets the testing standards such as IEC884, GB2099, GB4706, VDE, etc.

2、 Scope of application:Suitable for conducting heat resistance tests on electrical enclosures, external components, and plastics made of all insulation materials. The testing method is to place the specimen on a platform in a constant temperature chamber at 125 ± 2 ℃, and then press the specimen with the ball end of this device. After testing for 1 hour, take out the specimen and place it in cold water for 10 seconds, and then measure the indentation value. The diameter of the steel ball indentation should not exceed 2mm.

3、 Main parameters:

1. The pressure is 20N

2. Ball pressure diameter: R=2.5mm

fourUsage method

1. According to the test requirements, first place the ball pressure test device in the heating box for a sufficient amount of time to ensure that the device has reached a stable test temperature before the test begins.

2. Place the test component on the support base so that it is in direct contact with the support base.

3. Place the surface of the tested component in a horizontal position and press the steel ball against the surface. The test should be conducted in a heating chamber at the standard specified temperature.

4. After the test reaches the standard specified time, the ball is removed from the sample, cooled according to the requirements of the standard, and the diameter of the steel ball indentation is measured to determine whether it is qualified.
