Cincinnati Sub-Zero (CSZ) Testing Services now offers HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening) testing to help shorten new product development time, decrease production and warranty costs, and significantly improve product reliability. Most frequently used by original equipment designers and manufacturers in the electronics, automotive, aerospace, medical and industrial equipment industries, these accelerated test methods employ stresses significantly higher than field environments to uncover design and process weaknesses.
"HALT testing is primarily used during the product design phase to reveal any defects and make the product more rugged and reliable. HASS testing is principally used to screen for manufacturing defects by stressing the product without causing damage or a significant reduction of the product's expected lifespan," explains Glenn Kruschinski, Test Lab Director.
"The most commonly-tested products include printed circuit boards, power supplies, medical products, monitors/displays, avionics, gears, transmissions and GPS systems," he adds.
As a division of CSZ Products, Inc., CSZ Testing Services has access to the latest equipment and technology. CSZ's HALT & HASS testing equipment holds products with a footprint up to 2 x 2 feet and weighing up to 780 pounds. It provides extreme temperature change ramp rates of greater than 90 degrees Celsius per minute, and handles temperature ranges from -100 to 200 C. Random, multi-axis vibration levels from 1 to 90 GRMS can be attained with six degrees of freedom.
"For HALT testing, very little preparation time is required because we use temporary restraining straps or bars to secure the product, and moveable ducts for air stream positioning," continues Kruschinski. "HASS testing requires more time to implement because it must be preceded by a HALT test to determine the test profile, and usually requires unique fixturing that we can design and construct in our facility to accommodate the test."
All CSZ testing personnel are able to assist with this testing, while HALT & HASS testing consultants are available to help with the process if needed. Test technicians are also accessible to conduct and supervise a test that runs outside of business hours and into the evenings or weekends. The testing area can be secured to restrict access as needed. CSZ's HALT & HASS testing quotes are returned within 72 hours. Confidential, accurate and valid test results are delivered electronically and/or in hard-copy format within three to five days after testing.
In addition to HALT & HASS testing, CSZ performs shock, vibration, environmental, corrosion and climatic testing (including extreme temperatures and humidity changes) for companies nationwide. CSZ's testing laboratories, located in Cincinnati as well as in Detroit, are outfitted with the most current testing technologies, and are staffed by a team of on-site test technicians who coordinate a tailored, cost-effective testing solution to meet specific product development needs.
