Vibration and temperature test chamber
HALT/HASS "Sigma"
Weiss Umwelttechnik
This test cabinet is used for performance of combined temperature and multi-axial-random vibration tests. The object of HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening) tests is to discover faults in parts and components of diverse products.
In order to improve the product quality, the cabinet not only allows performance of vibration tests, but also of HALT/HASS tests. Faults are induced by excitation of fast temperature cycles and 3D vibration. The test cabinet "Sigma" consists of a test space with airconditioning components and a vibration test table. The asymmetrically designed test table is subject to controlled shocks from pneumatic actuators arranged underneath, so that up to 35grms can be measured with six different degrees of freedom, in a spectrum between 5 and 3000 Hz.
