In order to bring a reliable product to market in the shortest period of time, manufacturers need a method that stresses the product and determines possible design and manufacturing weaknesses. HALT HASS testing allows manufacturers the opportunity to remain competitive by offering test recommendations in the design phase or prior to the manufacturing release. HALT and HASS testing are performed to identify design weaknesses, improve product reliability and reduce life cycle costs. The purpose of HALT and HASS testing is to determine whether a product will remain reliable in its intended environment over a required duration of time.

Although both methods test the physical integrity of the products being manufactured - (which in turn earns trust and builds customer confidence), there are differences between them.


Highly accelerated life testing (HALT) in the initial stages and highly accelerated stress screening (HASS) in the later stage of product development will help ensure product quality.

While HALT is performed during the development stage, HASS is performed during the manufacturing stage and otherwise prior to shipment and sale. It guarantees ongoing reliability of the product and adheres to the design changes built during HALT.
