Automotive EMC Chambers: The Key to Product Safety and Reliability

Automotive EMC chambers are specialized laboratories used to test the electromagnetic compatibility (EMC) of automotive equipment. EMC is electromagnetic radiation emitted from a device or system that can interfere with the operation of other devices or systems.

Supported Tests

  • Electromagnetic emissions testing: This test measures the level of EMI emitted by the equipment.
  • Electromagnetic immunity testing: This test measures how the equipment performs when exposed to EMI.
  • Electromagnetic compatibility testing: This test verifies that the equipment meets both emissions and immunity requirements.


  • Accurate and reliable test results: Automotive EMC chambers control the exposure of the equipment to EMI, ensuring accurate and reliable test results.
  • Time and cost savings: Automotive EMC chambers reduce the exposure of the equipment to EMI, which can save time and money on testing.
  • Increased product safety and reliability: Automotive EMC chambers improve the equipment’s resistance to EMI, which can increase product safety and reliability.

Automotive EMC chambers play an important role in the automotive industry. These chambers help to ensure that automotive equipment operates safely and reliably.

CISPR 25 Chamber Dimensions

Chamber Type Total Required Space External Dimensions Internal Clearance
CISPR 25 ESA 5.50 m x 4.30 m x 3.50 m 5.50 m x 4.30 m x 3.30 m 4.62 m x 3.42 m x 2.86 m
18.04 ft x 14.11 ft x 11.48 ft 18.04 ft x 14.11 ft x 10.83 ft 15.16 ft x 11.22 ft x 9.38 ft
  • The total area required for an automotive EMC chamber includes the steel structure, door drive track, and HVAC ducts.
  • The external dimensions do not include the steel structure, so you need to take this into account when choosing a location.
  • The internal clearance is measured from absorber to absorber and from the ground plane to the absorber.
