Extreme Temperature Testing

PAMI operates two vehicle size environmental chambers at its Humboldt station that can generate extreme temperatures ranging from -50ºC to +60ºC. In conjunction, a smaller cabinet freezer can generate temperatures down to -85ºC.

These chambers make it possible to simulate extreme temperatures and their effects on components, vehicle/equipment structures or processes. PAMI can set up tests to meet the strict requirements of a wide range of testing standards. This ability assists clients ensure the safety and durability of their vehicles/ equipment or components or process performance. Following test procedures, a comprehensive report is prepared for the client outlining the types of tests performed, the data acquired, and analyses conducted.

Applications for the Environmental Chambers

  • Cold starting tests on diesel and gas engines
  • Product conditioning prior to testing
  • Testing of large equipment and components under extremely high or extremely low temperatures
  • Calibration of temperature sensitive equipment
  • ROPS tests (CSA Standard B352.0)
  • Implement/tractor electronic interface environmental tests
  • Engine cooling capacity tests
  • Cab windshield defrost tests (SAE Standard J381)
  • Cab defogging tests (SAE J953)
  • Cab heating and air-conditioning tests (SAE Standard J1503)
  • Cold filter plugging tests
  • Rubber and plastic hose flexibility, cold tests
  • Protective clothing temperature tests
  • Aerospace component tests
  • Reduced temperature component operation
  • Calibration of temperature sensitive equipment
  • Confirmation of finite element analysis heat transfer modeling
  • Composite material testing under force/vibration
  • Cold temperature food/feed processing.


  • Aiding in the design process, data collected at temperature extremes can prove useful to the designer during the product development cycle. Critical design information helps minimize machine production costs as well as warranty costs.
  • Confirmation of finite element analysis heat transfer models.
  • Computerized analysis allows the set-up of laboratory testing to accurately simulate field conditions.
  • Designs based on measured values are more accurate than those based on assumptions.
  • Minimized field testing reduces costs.
