MIL STD 461 Military Test Chamber

Specifically designed for the varied and heavy duty testing required by the military.


Global EMC’s MIL-STD-461 test facility has been specifically designed for the varied and heavy duty testing required by the military. The chamber is constructed using a self-standing steel structure and modular steel shield. Specially designed for MIL-STD-461, Global EMC use a compact and cost effective anechoic pyramidal absorber, bespoke to this standard. This increases the internal space within the chamber and helps reduce the overall cost. Due to the varied requirements of the equipment to be tested, all MIL-STD-461/DO-160 chambers are designed and manufactured to exact requirements.


Testing facility for performing compliant tests to MIL-STD-461 and DO-160. The chamber can be designed to test small electronic equipment to very large military vehicles. Communication and electrical equipment, armaments, aircraft equipment and vehicles are all examples of what can be tested.

The chamber can also be adapted to meet the requirements of DEF STAN 59-411 upon request.
