(HASS (Highly Accelerated Stress Screening Chambers for testing and screening in accelerated stress testing from Qualmark. Mapping known product weaknesses in mass production -60°C to 120°C at a rate of up to 60°C per minute. HASS testing chamber with 6 separate workstations for repetitive shock/vibration testing in rapid thermal cycling After acquiring American Qualmark, Espec is proud to offer an even wider range of chambers. Accelerated LIFE testing chambers (HALT) combine extreme cyclic temperature with vibrations/shock to achieve the most accelerated reliability tests. The technology has advanced from a simple thermal shock chamber with an independent vibration table and control to an integrated HALT/HASS system. Qualmark chambers have been known as market leaders since the introduction of the technology in the early nineties. The technology provides the extreme stresses needed to find defects not found by traditional methods.
