Markings Durability Tester Product overview：

1. BR-PV-MDT  Junction box identification durability tester Through connecting rod, the piston's motion direction and the measured surface angle are 45°+5°.

2. The 5N force makes the test piston produce elastic deformation and frictional movement on the tested surface.

3. Displacement of frictional motion: 1~4mm

4. Squeeze cycle: 10 times

5. The test piston moves to the tested surface at a speed of 60 mm/s and acts on the tested surface with a force of 5 N.

6. The time when the piston friction the detected surface is approximately the same as the time when the piston is lifted.

7. Force time: ≥0.2s

8. The frequency of the cycle is 2 + 0.5 cycles / second.
