Trucking Industry Testing - Clark Testing

Trucking Industry Testing


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 17025:2005 accreditation, certificate number L2163. 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

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.
