HALT and HASS Discussed in Layman’s Terms

Product TestBefore launching a product into the market, it is highly important that its quality and durability is tested and secured. Companies found a way to do this, minus the element of real time through accelerated stress test programs (AST). AST aims to expose the weakness of products to know how to improve it.

Difference of HALT and HASS

The two most common methods of accelerated tests are Highly Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS). Both methods use externally controllable variables to present a pseudo-environment that can test the product’s capacity.

HALT is designed to find a product’s weakness as quickly as possible through applied external stress, vibration, temperature, and frequency among others. Once found, a correction program would be made. The product would again be put into HALT, find the weakness and corrected again. This cycle goes on until the weakness can be virtually eliminated.

HASS, on the other hand, works like HALT where external stress and pressure is used to uncover flaws in the product at the shortest time possible. However, unlike HALT, HASS aims to uncover flaws in manufacturing such as shorts in circuits and joints. HALT uncovers designs flaws. The aim of HASS is to measure the reliability of the product itself.

Importance of your product

Correctly performed tests can reap your company numerous benefits and help save a huge amount of money. However, pinpointing the weakness is not enough. The means to correct these weaknesses should also be made. With such tests and the needed corrections made, your company would be able to launch your products earlier, reduce the cost of the warranty, reduce the cost of production and increase your market shares and profits.
