Designers Choose OTS
...because a well planned test protocol is key to a successful development project.
OTS works with electronic component designers to create testing programs that result in a high degree of design margin confidence at the lowest development cost.
Our diverse team of mechanical, electrical and materials engineers have over 20 years of testing experience specific to the survivability and reliability of embedded electronics subjected to high-intensity shock loads generated in gun-launch, space transport and other crash/high impact environments.
Testing Services Available to Meet Your Extreme Environment Requirements
Mechanical Shock Test
Mechanical shock testing is performed using a customized high-g shock table which is capable of providing a broad range of testing conditions compliant with industry and military standards. A test article is affixed/inserted into a custom designed test fixture which is then attached to the shock table mounting plate. The mounting plate is raised then released (dropped) from a prescribed height. High-g accelerations are achieved using a Dual Mass Shock Amplifer (DMSA).
Steady-State Acceleration Test
Steady-state acceleration testing is performed using a custom built, high speed spinning rig which is capable of simulating gun-launch testing conditions. A test article is affixed to the specimen mounting shaft that has a balanced and working cylindrical volume of 225 in³. Once mounted, a test article can be subjected to spin rates up to 250Hz in 10Hz increments. Acceleration loading can be held steady for test durations of up to 15 minutes.
Thermal Shock Test
Thermal shock testing is performed using a specially equipped benchtop dual chamber system which is capable of providing a broad range of testing conditions compliant with industry and military standards. A test article is subjected to air-to-air thermal shock with a cold chamber minimum temperature of -70°C and a hot chamber maximum temperature of 200°C. Test article transfer time from one chamber to next (under standard ambient conditions) is less than one minute.
Altitude testing is performed using a specially equipped stainless steel vacuum chamber which is capable of precisely simulating the low air pressure conditions associated at high altitudes. Once under vacuum, a test article can be subjected to simulated altitudes of up to 40,000 ft and a temperature range of 22°C to 200°C.
