Now Providing HALT & HASS Testing Services

CSZ HALT & HASS Testing ServicesCSZ now offers HALT & HASS Testing Services to help shorten new product development time, decrease warranty costs and significantly improve product reliability. CSZ’s HALT & HASS chambers incorporate extreme temperature change rates & random, multi-axis vibration with 6 degrees of freedom to rapidly uncover design and/or process weaknesses.

HALT techniques are important in uncovering many of the weak links inherent to the design and fabrication process of a new product. HASS techniques are incorporated during the production phase to find manufacturing process defects that could cause product failures in the field.

CSZ Testing approved by Defense Logistics AgencyCSZ has received laboratory suitability status approval from the Defense Logistics Agency, Defense Supply Center in Columbus, OH for multiple test methods. CSZ is deemed suitable to perform the following tests Fluid Immersion, Humidity and Temperature Cycling Testing along with Vibration, Shock, DWV at Sea Level, DWV at Altitude, and Salt Spray Corrosion Testing for products supplied to the Department of Defense.

CSZ Testing was formerly ESSC Test Lab

ESSC Test Laboratory changed its name to CSZ Testing Services to better symbolize our expanding range of environmental testing capabilities. We believe this change will allow us to align all three divisions of Cincinnati Sub-Zero and build from the strengths of each division. As always, we will continue to provide you with the highest level of service, expertise and quality while utilizing the latest test equipment technology from CSZ to test all products.

Expanded Thermal Shock Capabilities

Thermal Shock CapabilitiesCincinnati Sub-Zero Test Laboratory has expanded its test capability with their oversized thermal shock chamber which is 144 cu. ft. and is rated to hold up to 600 lbs with a transfer rate of 12 seconds.

This chamber was initially used to test head curtain air bags up to 8’ long. Other products are also tested in the large thermal shock chamber such as hybrid batteries weighing up to 150 lbs. and 3-4’ long with basket dimensions of 4’ x 4’ x 8’. This also allows the laboratory to test multiple products at one time increasing throughput and minimizing test time.
