HASS (High Accelerated Stress Screening)

Once a HALT test has been performed on a product, HASS (High Accelerated Stress Screening) can be utilized to complete your continuing compliance program and ensure that your product still meets the reliability standard that was achieved during the design and prototype phase. This process is not only utilized by manufacturers during pre-product release, but most often later in a product’s life when components become obsolete and must be replaced or a new manufacturing location has been selected.

Understanding HASS Testing Limits

The HASS process does not push the product to destruction as during the HALT testing. Rather limits for combined stresses (temperature and vibration) are performed at test levels over the operational limits and under the destruction limits determined in the earlier HALT testing.
