HALT Testing and HASS Testing

Highly Accelerated Life Testing and Highly Accelerated Stress Screening

HALT / HASS stands for Highly Accelerated Life Testing / Highly Accelerated Stress Screening. These blue steel chambers provide critical data about your product’s reliability and maturity. Expert operators conduct testing with HALT / HASS equipment at several Stork locations in the U.S., providing extremely accurate simulations of real-life conditions your product or parts may endure.

Mean Time Before Failure

Stork offers its clients HALT / HASS services for a variety of testing applications, including evaluation of a product’s design before it enters the production phase. It is an invaluable tool for increasing a product’s Mean Time Before Failure (MTBF). Engineers have recorded increases from 5 to 1000 times original MTBF with strategic use of HALT / HASS testing.

Shorten Time-to-Market

Stork engineers and scientists have substantially reduced the research and development costs in time and labor for countless clients with HALT/HASS services. It is a proven method of shortening the time-to-market period. Our experienced staff has the training and expertise to apply the many benefits of HALT/HASS testing—as well as those of all our specialized instrumentation and equipment—to your specific product or process.
