Rail Industry Testing - Clark Testing

Rail Industry Testing

Clark Testing has a long history of mechanical testing, equipment qualification and product validation for the heavy and light rail industry. We have provided testing services for locomotive and freight car equipment manufacturers along with component testing services for passenger rail cars and people movers.

Our fully accredited ISO 17025-2017 labs have provided comprehensive testing services for the rail industry such as structural, vibration, thermal, load & fatigue, life cycle aging and EMC/EMI testing. Clark’s testing and validations services to railcar manufacturers are in accordance with AAR, APTA, EN, MIL-STD, ISO and IEC Standards.

Testing Services on Railcar Components

Clark’s engineers collaborate with our customers to develop test programs to simulate the operating environment and functional operation of their specific components. These programs are designed to meet the industry testing standards and customer specifications.

Typical test objectives include:

  • Design verification and certification according to a specific standards or client specifications.
  • Component performance characterization and validation to comply with contract requirements.
  • Finite element analysis and root cause analysis

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.
