An unbiased data sheet


Vehicle EMC test chambers can be similar to a standard EMC test chamber (see CISPR16 test chambers)


Some vehicle test chambers are designed specifically for radio work (80MHz+) in this case the anechoic lining tends to be pyramidal absorber only.


The difference between a standard EMC test chamber and a vehicle test chamber is:


  1. The door entrance has to be large enough, normally double doors or sliding doors are used for this purpose
  2. The chamber entrance requires fixed, moveable or energised entry ramps
  3. If the chamber is required to cater for ‘hot engine’ then the chamber will require high volume air movement.
  4. Some chambers are directly connected to air conditioning (HVAC) systems
  5. The exhaust fume extraction system is required.
  6. The chamber has to be large enough so that the vehicle doors can be opened without hitting the absorbers.
  7. The floor of the chamber and the turntable (should there be one specified) are capable of withstanding the loads.
  8. Other desirable facilities may be carbon monoxide warning systems & special lighting.
