HALT - Vibration Step Stress
Vibration step stress consists of increasing the vibration level in 5 Grms steps until the Operating & Destruct Limits are found. The products functionality is checked at each step. The temperature is held at an ambient temperature of ~30°C.
Brief Vibration Step Stress Summary
The Unit Under Test (UUT) is mounted onto the vibration table using a fixture that
is thermally transparent, lightweight, and rigid. Accelerometers are attached to the UUT
to monitor the response of the product. The test is conducted at an ambient air temperature
and begins at 5 Grms, with a minimum dwell time of 15 minutes. Testing
is conducted on the product to ensure full functionality is attained.
After the dwell period has expired the vibration is stepped up
in 5 Grms increments, and the dwell time repeated.
