HALT generally consists of five types of stresses, which are sequentially performed in order to determine the operating and destruction limits of the product with respect to temperature, vibration, and/or combination of the two. This methodology is successfully used by automotive, computer, oil and gas instrumentation companies, etc. to release a more reliable product.

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.
