HALT/HASS Testing
HALT HASS Chamber
AST applies stresses (such as temperature and vibration) to products well beyond its normal use environment. This type of testing is done to determine product operating and destruct limits. These stresses are applied as the product is functionally tested and continuously monitored for failures.Highly Accelerated Stress Testing (HALT) and Highly Accelerated Stress Screening (HASS) are two types of accelerated stress testing. These types of tests are commonly used to eliminate design problems, helping to develop a robust, mature product prior to market introduction. It can also be used to screen out infant mortality issues prior to shipment.

Highly Accelerated IOL
Best Electronics and Components Co., Inc.
MEASUREMENTS ARE CONTINUOUS - The advantage is that rather than waiting for read points on the device for example at 500 temperature cycles, 1500, 7500 15,000 temperature/power cycles etc, the data is continuously gathered and so devices that are damaged by the cycling are seen much earlier. USEA has seen apparently "good" arts fail in as little as 200 temperature/power cycles. The implication to our customers is they have an accelerated warning that a lot is going to fail the IOL study.

HALT – Highly Accelerated Life Test
HALT is a process used on electronic assemblies and modules to determine weaknesses and the stress limits of a product by temperature cycling and omni-axial random vibration step stress. Inherent weaknesses in a products design and build are stimulated by applying increasing levels of mechanical stress. Within an accelerated timescale, faults in a product can be realised prior to product release and preventing failures occurring during after-sale user operation, very often during the warranty period.

Heat Stress Meters
The heat stress meter is mainly used in the workplace. The heat stress meter can detect and classify temperature in relation to the amount of moisture content. What is heat stress? And why is heat stress measured? People who work in installations or with machines that produce a lower energy level or a high emission of temperature can occasionally suffer heat stress (by the influence of body temperature). This phenomenon can also cause physiological symptoms: spasms, feeling unwell and shock that can in some cases prove fatal.
