DEF STAN 59-411 Military Test Chamber

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


Global EMC’s DEF STAN 59-411 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 the increased performance to DEF STAN 59-411 compared with MIL-STD-461, Global EMC uses GF 102 ferrite tile and high performance pyramidal Hybrid Absorbers.

Due to the varied dimensions and requirements of the equipment under test (EUT), all DEF STAN 59-411 chambers are designed and manufactured to exact requirements.


Testing facility for performing compliant tests to DEF STAN 59-411, MIL-STD-461 and RTCA 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.
