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.

WEIBER provides humidity resistance evaluation test for electronics components through customized Extremely Accelerated Stress Test Chamber. This chamber provides high performance test in minimal amount of time according to international IEC 60068-2-66 standard. This chamber also known as Accelerated Stress Test Chamber, Halt and Hass Test Chamber, Halt Test Chamber and Hass Test Chamber.This chamber reduces the time taken for humidity testing in electronic components. 2 types of tests saturated and unsaturated extremely accelerated stress test can be performed. In saturated test the temperature is maintained at 1210C at 100%RH, and for unsaturated temperature of 110, 120, 1300C is maintained at 85%RH. Normally for electronic components unsaturated type test is done.

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.

Acceleration Testing
The acceleration test is performed on a centrifuge to assure that material can structurally withstand the steady state inertia loads that are induced by platform acceleration, deceleration, and maneuver in the service environment, and can function without degradation during and following exposure to these forces. Acceleration tests are also used to assure that material does not become hazardous after exposure to crash loads. The acceleration test method is applicable to material that is installed in mobile platforms such as aircraft, helicopters, aerospace vehicles, air-carried stores, ground-launched missiles, trains, ships, automotive vehicles, etc.

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.
