ASLi ISO 16750-3 MS-50 Mechanical shock testing machine

1. Mechanical shock : Test for devices in or on doors and flaps

2. Purpose: This test checks the DUT for malfunctions and breakage caused by shock of door slamming.

The load occurs on closures when slammed shut. Failure mode is mechanical damage(e.g. a detached capacitor inside the housing of an electronic control module due to the high accelerations caused by door slamming).

3. Test : The DUT shall be fixed on the shaker in a direction to generate the effect of acceleration in the same direction as it occurs in vehicle use.

4. ISO 16750-3 standard:

Shock profile 1:

Pulse shape: half-sinusoidal,

Acceleration: 500m/s2

duration:11ms

Shock profile 2:

Pulse shape: half-sinusoidal,

Acceleration: 300m/s2

duration:6ms

5. IEC 6008-2-29 Standard

Pulse shape: half-sinusoidal,

Acceleration: 500m/s2

duration:6ms

Number of shocks: 10 per test direction

Acceleration due to the shock in the test shall be applied in the same direction that the acceleration of the shock occurs in the vehicle. If the direction of the effect is not know, the DUT shall be tested in all six directions.
