Global EMC's DEF STAN 59-411 Military EMC Test Chamber Facillity for Defense Standards Qualification 712370

Global EMC, a UK-based manufacturer and installer of anechoic test chambers, Faraday cages, RF shielding systems and magnetic field shielding solutions for EMC and RF testing applications, offers a DEF STAN 59-411 Military EMC Test Chamber designed for military electromagnetic compatibility (EMC) testing and inspection of critical components used in defence qualification programs. Built using a self-supporting steel structure and modular steel shielding, the chamber is designed to meet DEF STAN 59-411 requirements, which are more stringent than comparable US military standards.

The chamber supports testing for DEF STAN 59-411, MIL-STD-461 and RTCA DO-160, enabling evaluation of equipment ranging from small electronic devices to large military vehicles. It can be used to test communication and electrical equipment, armaments, aircraft equipment and military vehicles. The facility also performs shield attenuation testing in accordance with EN 50147-1.

Designed to customer-specific dimensions and equipment requirements, the facility incorporates GF102 ferrite tiles and high-performance hybrid pyramidal absorbers to support EMC testing. It provides a dedicated environment for measuring and analysing conducted emissions, conducted susceptibility, radiated emissions, radiated susceptibility, and electrostatic discharge. The EMI/RFI shielded room uses the Faraday cage principle to prevent external electromagnetic signals from affecting testing.

The chamber is lined with gapless hybrid pyramid absorbers and ferrite tiles across the walls and ceiling, with absorbers engineered to provide a smooth transition between low- and high-frequency performance. Its plug-in absorber design allows individual absorber cones to be replaced if damaged, reducing repair time and maintenance costs. Standard shielding is suitable for most commercial testing applications, while an extended shielding option is available for military and high-frequency testing requirements.

Key features include compliance with DEF STAN 59-411, anechoic performance, EN 50147-1 shielding effectiveness, a 1-metre measuring distance, configurable chamber layouts, low-maintenance shielded doors with copper-beryllium knife-edge seals, GF102 ferrite tiles on walls, ceilings and floors, moulded polystyrene hybrid absorbers, specialist filter options and grounded conductive test benches.

The chamber is constructed with a self-supporting steel frame and modular 2 mm steel panel shielding. Standard specifications include a shielded pedestrian door with a 1000 mm x 2000 mm clear opening, four 300 mm × 300 mm honeycomb ventilation panels for static air flow, and penetration panels with two Precision N-type connectors and two fibre connections.

Additional configuration options include masts, fire detection systems, vehicle sliding doors, HVAC, CCTV, test benches, vehicle fume extraction, absorber whitecaps, lighting, power, turntables, heavy floor loading, DC sockets, filters and audio communication systems. Chamber dimensions can be customised to meet specific application requirements.
