DEF STAN 59-411 Military Test Chamber
Global EMC’s DEF STAN 59-411 Military test chamber facility has been specifically designed for the varied and heavy-duty testing required by the military. DEF STAN (UK Defence Standardisation) 59-411 is the equivalent of, yet more stringent military standards of the US related MIL-STAN.
The chamber is constructed using a self-standing steel structure and modular steel shield and is used for the EMC testing and inspection of critical components of defence qualification programs.

RTCA DO-160
RTCA DO-160 (aerospace) test procedures; a standard for the environmental testing of avionics hardware
Shield Attenuation
Fully compliant emissions testing to EN 50147-1, a BSI standard for validating shielding effectiveness.
Military Testing
Built to MIL-STD-461 standards for the control of electromagnetic interference (EMI).
This Product Features
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.
Global EMC’s DEF STAN shielded test facility uses GF 102 ferrite tile and high-performance pyramidal Hybrid Absorbers.
DEF STAN 59-411 Military EMC Test Facility
DEF STAN 59-411
A dedicated military EMC test facility for the measurement and analysis of conducted emissions, susceptibility, radiated emissions, radiated emission, radiated susceptibility and electrostatic discharge.
Military
Specifically relating to UK defence standardisations.
EMC
Electromagnetic compatibility or EMC testing gives the manufacturer of a product the ability to demonstrate the ability of their product.
Test Facility
An EMI/RFI shielded room, using a Faraday cage principle. This is to stop unwanted signals from the ambient environment entering the chamber and causing interference whilst tests are being performed.
High-Performance Anechoic Lining
Ferrite Tiles & Absorbers – The walls and ceiling of the test chamber are precisely lined with the latest generation gapless Hybrid Pyramid absorbers and Ferrite tiles. The Pyramidal absorbers are precisely doped to ensure a smooth transition between the high performance of the Ferrite tiles at lower frequencies to the Pyramidal absorbers in higher frequencies. The “plug-in” base system of the absorbers means that individual absorber cones can be replaced if accidentally damaged during operation of the test chamber. This reduces the cost of repairs and time taken for the test chamber to become fully operational again.

Shielding Effectiveness tested to EN 50147-1
Every Global EMC anechoic chamber is provided with a Faraday cage shield. The shielded enclosure provides both an area free from external ambient signals but also protection during Immunity testing for personnel working outside the chamber.
The measure of shielding performance is conventionally known as “shielding effectiveness”. 100dB in plane and microwave frequencies is generally regarded by most standards as a very high level of shielding suitable for scientific use.
Global EMC offer two levels of shielding Standard and Extended Performance. Standard performance is suitable for most shielding requirements and is typically seen in commercial testing situations. Extended Performance is usually used in high-performance Military applications along with certain high frequency needs.
