Vehicle Environmental Test Chambers

JCB being tested at low temperatures.

MIRA's whole-vehicle environmental test chambers are for extreme temperature testing with humidity and solar loading options.  The chambers can be programmed to perform cyclic profiles such as Def Stan 00-35 and MIL-STD 810G.  The two chambers each accommodate a passenger car separately or, when linked together a commercial vehicle.

Typical tests performed in the chambers include:

  • Hot and cold start tests
  • Heating and air conditioning performance evaluations
  • Windscreen/window defrost/demist tests
  • Functional, durability and structural assessment in extreme environments
  • Component and material performance assessments
  • Controlled thermal 'soaks' and solar radiation assessments

MIRA's whole-vehicle chambers are just one part of our suite of environmental test facilities which include climatic wind tunnels, laboratory environmental chambers and combined environmental and durability test facilities.
