Electromagnetic Environmental Effects (E3)

The KBR team of experienced engineers and technicians deliver high-end solutions that safeguard our customers’ most valuable designs with sophisticated tools, hardware and training. KBR unveiled its own Electromagnetic Interference & Compatibility Testing Laboratory (EM Lab) in Warner Robins, Georgia, to meet increasing demands for EMI/EMC testing closer to Robins AFB. KBR tests internal designs and our MIL-STD-461G test capabilities meets the needs of our customers.

Areas of Expertise

KBR’s EM lab helps our customers accomplish their Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) testing. The KBR EM Lab capabilities include:

Frequency Ranges:

Capable of covering frequency ranges from30Hz to 18GHz with anticipated capability to 40GHz.

Design and Construction:

Designed to provide the best performance in a restricted size format. Constructed with materials including, but not limited to, ferrite, polyethylene closed cell foam, and oblique incidence absorbers to provide superior performance – minimizing energy reflection and maximizing absorption over a broad frequency range within the testing chamber.

Testing Chamber:

Chamber dimensions 40’ x 13.5’ x 10.5’ (L x W x H) that supports equipment under test sizes up to13.3’ x 4.5’. Available power for equipment is:

• 0-32VDC/384W

• 115VAC/60Hz/20A

• 208VAC(2-phase)/60Hz/30A

• 208VAC(3-phase)/60Hz/30A

• 200VAC(3-phase) /400Hz/30A

Testing and Reporting:

Testing is performed and recorded with ETS-Lindgren TILE!. Comprehensive reports are generated in Microsoft Word, Excel, or PDF format, providing extensive details of test results and equipment used (calibration dates included in reports).

Quality Management:

A quality management system that maintains strict adherence to ISO-STD-17025 to ensure the EM Lab operates in accordance with industry and government standards.

Secure Facilities:

The chamber is inside a secure facility that is monitored 24/7. The laboratory entrance is secured by badge swipe door locks and limited access. The laboratory loading dock is secured by locked steel doors with alarms.

Electromagnetic Compatibility Testing:

Tests in the EM Lab include radiated susceptibility, radiated emissions, conducted susceptibility and conducted emissions.

• Radiated emissions tests determine the strength of RF signals emitting from a device.

• Radiated susceptibility tests determine the susceptibility of the equipment under test (emissions from surrounding equipment can impact the operations of the unit).

• Conducted susceptibility testing simulates disturbances from other equipment powered on the same network and checks the external input and output cabling (often times bundled together) to ensure it is able to withstand potential disturbances.

• Conducted emissions tests (the inverse of conducted susceptibility tests) measure the emissions, or noise, propagating from the equipment cabling.

ISO/IEC 17025 Accreditation:

KBR expects the EMI/EMC lab to be ISO/ IEC 17025 accredited by March of 2024. Once accredited, the KBR lab will be the only certified facility within a 130-mile radius of Warner Robins AFB.
