HALT HASS Testing
TÜV SÜD undertakes HALT (highly accelerated life testing) and HASS (highly accelerated stress screening) for manufacturers.
The intention of HALT is to rapidly improve product reliability at an early stage in a product’s life and consequently reduce costly in-field failures and warranty claims. Throughout the HALT process, the intent is to subject the item under test to stimuli well beyond the expected field environments to determine its Operating and Destruct limits.
Any Operating and Destruct limits discovered during HALT can be used, to develop an effective Highly Accelerated Stress Screen (HASS) for manufacturing. HASS will quickly detect any process flaws or new weak links without taking significant life out of the product. The HASS process will ensure that the reliability gains achieved through HALT will be maintained in future production.
Our technical expertise and experience enables us to create meaningful HALT testing programmes and assist you in identifying and characterise flaws in design, in order to produce a more rugged and reliable product.
