Accessories Mechanical Strength Impact Test Apparatus For EV Testing IEC 60309-1
The experimental principle is that after the gravitational potential energy is converted into kinetic energy, the equivalent mass impact weights will be freely released at a certain height to achieve the required impact energy.
The mounting bracket can be adjusted in three-axis, front and back, up and down, and left and right, which has strong applicability.

Counterweight and impact energy For Accessories Mechanical Strength Impact Test Apparatus:
Choose the counterweight and drop angle according to the impact energy. If the impact energy is ≤2J, add two counterweights at the upper hole position and with one weight on each side, the total mass is 0.5kg; if the impact energy is >2J, add two more counterweights at the lower hole position and with two weights on each side, the total mass is 1Kg.
Counterweights of the impact energy and the impact angle are shown in following Table:
| Impact energy(J) | Counterweights(Kg) | Release angle |
| 1 | 0.5 | 25° |
| 2 | 0.5 | 35° |
| 3 | 1 | 36° |
| 4 | 1 | 42° |
| 5 | 1 | 47° |
| 6 | 1 | 52° |
1 No-load impact is strictly prohibited for the device, that is, there should be objects during impacting.
2 The screw must be frequently lubricated to prevent rust.
3 Required environmental conditions: temperature 5℃~35℃, humidity 45%~75%.
