Testing Services


Clark Dynamics has the environmental chambers to accelerate aging and validate functional performance for longer product life expectancy. Clark can accommodate large component aging for extended periods simulating containment internal conditions as high as 170C.

Electromagnetic Compatibility (EMC)

Common to automated systems and electronics in the industry is the requirement to ensure electromagnetic compatibility of components and mitigate vulnerability to outside sources. Emissions and Immunity analysis provides insight as to the potentially undesirable propagation and reception of electromagnetic energy and radiofrequency interference.

Structural, Load and Fatigue

Unique to each test specimen are its functional and design-basis lifetime requirements. Clark’s facilities have the equipment and technical expertise to test a variety of components for mechanical fatigue and failure, life cycle, aging, accelerated aging, and simulation that is common to the automotive industry.

Shock and Vibration

Clark Testing’s Vibration laboratory has multiple hydraulic and electrodynamic shakers making Clark Testing the ideal fit for all your testing needs. Our Vibration laboratorys' investment in new equipment has led to Clark Testing being an industry leader in Vibration Testing.
