Testing that Reaches the World
Trucking Industry
Clark Testing has a long history of both component and full vehicle validation and testing services for truck and trailer manufactures. Our engineers have many years of experience in stress analysis, strength and fatigue testing of structural components, beam fatigue and systems. Our laboratory is proud to continually maintain its certification to ISO/IEC 17025. The Clark TestingStructural Testing Laboratory also specializes in ROPS/FOPS testing, dynamometer testing, and rotary fatigue testing.
Certification and Standards
- SAE
- ASME
- ANSI
- FMVSS / CMVSS
- ISO
- MIL-STDs
Clark Testing provides cab safety certification with our ROPS, FOPS, and TOPS testing services in accordance with SAE J/ISO 3471. We qualify structures and cabs typically installed on almost any type of operator driven or stationary machinery. These ROPS, FOPS, and TOPS tests insure the protection and safety of operators from a rollover (ROPS), tip over (TOPS), and a falling object (FOPS). Clark Testing has facilities and capabilities to perform destructive testing of large off highway equipment requiring extreme loads in excess of 1 million pounds.

Testing Services
Structural, Load & 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.
ROPS / FOPS
Clark’s structural laboratory provides ROPS, FOPS & TOPS testing services in accordance with SAE J/ISO 3471 to qualify structures and cabs typically installed on almost any type of operator driven or stationary machinery. These ROPS, FOPS, & TOPS tests insure the protection and safety of operators from a rollover (ROPS), tip over (TOPS) and a falling object (FOPS). Clark Testing has facilities and capabilities to perform destructive testing of large off-road equipment requiring extreme loads up to 1 million pounds.
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.
Powertrain and Gearbox
Clark Testing has been in the powertrain & gearbox testing business for over 20 years. Over that time we have tested products ranging from small components such as starters and air motors to transmissions and axles in excess of 2000 horsepower. ciency for anything from heavy off-road industrial equipment to high performance motorized competition vehicles.
