EMI Testing / EMC Testing

Experienced EMI / EMC testing can reliably predict product performance in any electromagnetic environment. Testing can also determine the possibility of interference with other equipment, possibly degrading performance. Testing may be required to comply with regulations or for informational and product-improvement purposes.

Electromagnetic compatibility (EMC) testing requires appropriate electrical and structural design, equipment installation, wiring installation, and equipment qualification.

Electromagnetic Interference (EMI) testing is performed to ensure that your product will perform properly when subjected to the electromagnetic environment in which it is expected to operate.

Systems should be compatibility-tested to electromagnetic effects originating systemically such as electronic noise emissions, self-generated RF transmissions from antennas, and cross coupling of electrical currents. Also considered are externally occurring effects including lightning, electromagnetic pulse (EMP), electrostatic discharge and man-made RF transmissions.

EMI / EMC Testing for the Military

DTB offers exceptional Electromagnetic Pulse (EMP / Method RS105) testing and owns the largest RS105 simulator of its kind by far, in any U.S. non-government test facility.

This test is applicable to equipment and subsystem enclosures when the equipment or subsystem is located externally to a hardened (shielded) platform or facility. It is also applicable for equipment intended solely for use on non-metallic platforms. In addition, the requirement is also applicable to Army aircraft for safety critical equipment and subsystems located in an external installation. The military needs to ensure that critical equipment survives and/or works properly in circumstances.

Shielding Effectiveness Testing

electro-shielding-testing

Shielding Effectiveness Testing —  DTB has over 50 years of Shielding Effectiveness (SE) experience from 1960’s era aircraft harnesses through latest in Ethernet CAT-7 cables and composite materials.

There are dozens of shielding effectiveness (SE) specifications in the military and commercial worlds with, most designed to provide a tool for quality control for specific materials. We have specialized in adapting these specifications to develop tests to evaluate shielding effectiveness in real world conditions.

StirredModeTestIn conjunction with the U.S. Navy, Dayton T. Brown constructed one of the first large stirred mode chambers to test the shielding effectiveness of large armament systems.

Many of our customized test approaches have been incorporated into product development specs or test specs.

We can test in accordance with IEEE 299, MIL DTL 83528C, IEC 61726,ANSI/SCTE 48-1 and Mil STD 285 and we have performed Shielding Effectiveness testing on hundreds of items including the following:

  • Rooms – shielded and unshielded
  • Cabinets – system racks, equipment enclosures
  • Panels – metal, composites, laminates, glass, fabric
  • Cables – power, RF, communications, Ethernet, etc.
  • Connectors
  • Gaskets
  • Special/Unique – aircraft fuselage, torpedo hull, aircraft engine cowling

New products or applications also undergo environmental and vibration evaluations in our lab. We have performed specialized tests such as combined temperature/vibration to assess pin chatter in connectors, cold temperature bend radius for cables, or long term corrosion tests on composite panels, just to name a few

EMP - Electromagnetic Pulse Testing
Dayton T. Brown can perform all the EMP test methods described above. In fact, DTB now owns and operates the largest RS 105 EMP simulator of its kind in any U.S. non-government test facility!

An Electromagnetic Pulse (EMP) is defined as a high amplitude, short duration, and broadband pulse of electromagnetic energy. EMP is the electromagnetic effect resulting from the detonation of a nuclear device at high altitudes (also known as HEMP, HAEMP and HNEMP). EMP is a serious matter because it can have devastating effects on unprotected electronic equipment.

EMPMIL-STD-461 provides radiated (RS 105) and conducted (CS 116) test methods and test levels for determining a device’s immunity to EMP. The coupling modes into the equipment enclosure and its interconnecting cabling can be complex and are, therefore, evaluated separately.

The RS 105 test method addresses the risk of radiated exposure to an EMP event. Testing is generally applicable to equipment installed in exposed and partially exposed environments on aircraft, surface ships, submarines and ground vehicles.

The CS116 test method addresses the effects of EMP coupling onto interconnecting wiring harnesses. The goal of this test is to ensure the equipment’s immunity to damped sinusoidal transients induced on the equipment’s cables. Testing is generally applicable to all applications with limited applicability to submarine equipment.

The MIL-STD-188-125 establishes minimum requirements and design objectives for high-altitude electromagnetic pulse (HEMP) hardening of fixed, ground-based facilities that perform critical, time-urgent command, control, communications, computer, and intelligence (C4I) missions. Similar to the approach described in MIL-STD-461, this standard provides both radiated and conducted test methods and test levels.
