Test Spheres (Test probe A and Φ12.5 Steel Ball)

Test spheres are designed according to IEC61032 and IEC60529, includes test probe A (Φ50 sphere with hand), test probe 1 ( Φ50 sphere) and test probe 2 (Φ12.5 sphere). For the test of verifying the protection of persons against access to hazardous parts, usually it request 50±5N force to be applied for probe A and probe 1, and 30±3N force to be applied to test probe 2.

Usage

1) As shown in the figure, the sphere can not contact with the live parts or can not approach to hazardous parts.

2) For the test of approach to hazardous parts, probes without thruster should work with a force gauge to apply 50±5N (30±3N) force.

Notice:

1) Be careful for creep down to harm human body and sample.

2) It requires periodic maintenance, and keep it rustless.
