Ten Things You Should Know About HALT & HASS

HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Testing) are relatively new test methods. They are used on many products worldwide, ranging from consumer products to aerospace equipment. HALT is used during design and HASS is used during production. Both of these methods are fundamentally different from conventional test methods, because the objective is to intentionally cause failure to occur during the test, and not to demonstrate compliance with performance requirements. It is therefore often difficult for engineers, and especially technical management, to fully understand the principles of HALT and HASS. This presentation provides an overview of the process of performing HALT and HASS. Ten aspects, considered to be essential to understanding these test methods, are briefly discussed. The presentation is not a detailed technical discussion on the topic, but rather a management overview of principles required for successful HALT and HASS implementation.

Key Words: Reliability Engineering, HALT, HASS, Highly Accelerated Life Testing, Highly Accelerated Stress Testing
