What is Highly Accelerated Life Testing (HALT)?
HALT (or Highly Acclerated Life Testing) is a product reliability test that takes place during the design process in order to discover the weak links of a product prior to design completion. A stimulus is applied to a component as part of a fully functional product, or to the product as a whole to determine weak links or mismatches. Additionally, other types of stimuli are applied to determine points of failure, such as:
The highly accelerated life test conditions are such that the product is expected to break, eventually. The “successful” HALT test is one in which the product fails as the designer expects under the expected conditions of the product design. By finding the failure points for each critical component a better product emerges. Call today for your FREE Consultation! 303.444.7480 Back to Reliability Margins
What’s the difference between ALT, HALT, HASS Testing procedures?
The stresses applied during a HALT test are not meant to simulate those expected in the field but rather are to expose any weak components that should be upgraded to produce a more reliable end product.
The different varieties of accelerated stress testing are as follows:
Why use Percept for your HALT?
Percept has been providing quality and dependable reliability testing, including HALT, since 1996 to the Boulder, CO area as well as nationally. Percept understands that if the wrong tool is used or the right tool is misused, product reliability data can be inaccurate ending in disastrous problems for the company. We strive to produce accurate data analysis so that you can be confident that when a finished product is manufactured, it will be reliable and reputable.
