Accelerated testing is used to quickly detect any inherent design and manufacturing flaws. The environments are meant to give high levels of stress to precipitate failures in less time than in standard testing. Once the failures have been detected, corrective decisions can be made. This process adds to product robustness. The main element of the testing process is the HALT test. Typically, a series of individual and combined stresses such as multi-axis vibration, rapid temperature cycling and product power cycling are applied in steps of increasing intensity {well beyond those expected in the field). Test time is compressed with the accelerated stressing, leading to earlier product maturity.

What is HALT?

HALT - Highly Accelerated Life Testing

This is the process by which a product is tested, usually in its design or prototype stage, using temperature, vibration, and the combination of environments to test until the point of failure, typically using step stress methods. If the failure is unexpected, or below the limits deemed acceptable for its useful lifetime, then corrective action is taken, and the testing continued.


The Accelerated Life Test can show you, often in just a matter of hours, how a particular product will stand up to years of operational life.


By using the ACS UHS System, you can submit your product to extremes of environmental stress. You can perform various accelerated stress tests like HALT. HASS, Step Stress Testing and others. Each type of stress identifies specific defects that may be missed by traditional testing methods and equipment.


When these defects are speedily identified in the product development stage, it helps to reduce development time and produces higher quality product. Shorter development time means shorter time to market, something that can make a huge difference in sales. Higher reliability during the operational lifespan reduces warranty costs and general in-the-field repair costs. It also brings about customer satisfaction, something that is invaluable in a tough economic climate.
