Highly accelerated life test. A highly accelerated life test (HALT), is a stress testing methodology for enhancing product reliability. HALT testing is currently in use by most major manufacturing and research & development organizations to improve product reliability in a variety of industries, including electronics, computer, medical and military. HALT can be effectively used multiple times over a product's life time.
