Highly Accelerated Stress Screening (HASS) Test
HASS consists of high and low temperature and 3 axis vibration testing performed either individually or in combination.Highly accelerated stress screening is a technique for identifying process flaws in equipment during production. HASS subjects equipment to overstress conditions but at a level which does not affect design life.For assistance in designing a HASS test program contact the laboratory.

Extremely Accelerated Stress Test Chambers
The extremely accelerated stress environment is defined by high temperature, high humidity and high pressure. 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.

Environmental Stress Screening
ESS
Environmental stress screening (ESS) is also known as Burn-in, AST (Accelerated Stress Testing), HALT (Highly Accelerated Stress Test), or HASS (Highly Accelerated Stress Screening). Whatever the name, the idea is the same: create a test program that allows you to eliminate the infant mortality of your product.

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.

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.
