HALT (Highly Accelerated Life Testing) is performed on a product as part of the design process. Typically it is performed an a product when pre-pilot or pilot run units are available, before the design verification begins. During a HALT, a product is stressed far beyond what the product will encounter in a typical use environment. The actual functional and destruct limits of the product are found and pushed out as far as possible. These limits are used as the basis for the implementation of the HASS (Highly Accelerated Stress Screening) process during normal production of the product. HASS is a production screening test, performed on products built as part of the production process. The goal of HASS is to catch production run induced errors and weak link components that would otherwise fail in the field, thereby quickly weeding them out and fixing them prior to release to the customer.
