EMC/EMI

Environ has become an industry leader in the EMI field of testing. We have achieved this by drawing upon more than 40 years of testing to sophisticated military and aerospace specifications combined with the most modern equipment available and highly skilled engineers and technicians.EMI Chamber

Numerous chambers and ground plane rooms allow for flexibility in meeting your schedule.
We welcome the opportunity to consult with you about your program and offer guidance if needed.

Need a test plan that will be accepted by your customer and the FAA? No problem, we
routinely write custom test plans that will assure acceptance and keep you on schedule.

 

Highlights include:
  • HIRF, testing at levels greater than the highest CW/SW/Pulse requirements of Airbus, Boeing, and the FAA (>10,000 V/m!), automated, with any frequency step size.
  • Multiple burst and multiple stroke Lightning, Level 5
  • High current/voltage Power Input testing, both AC and DC
  • Fully automated testing
  • Radiated Susceptibility greater than 200 Volts/Meter
  • Multiple semi-anechoic chambers
  • Multiple reverb chambers
  • GTEM

High Intensity Radiated Fields - HIRF

New rules by the FAA, along with new requirements by some aircraft manufacturers, have led to significantly higher HIRF test levels for many aircraft electronic systems.

In response to these changes, Environ Laboratories, has positioned itself to provide HIRF testing at the highest levels required by commercial, military, and aircraft manufacturer standards. Using our 2 Reverberation Chambers, and our 3 Anechoic Chambers, we can perform HIRF testing at test levels that fully meet and exceed these requirements:

  •  FAA HIRF Rule and Advisory Circular 20-158
  •  RTCA/DO-160E/F, Category A - L, ALL CW, SW, and Pulse test levels
  •  Boeing D6-16050-5, ALL CW, SW, and Pulse test levels
  •  Airbus A400M, ALL CW, SW, and Pulse test levels, including:
    •  Pulse @ 3500 V/m, 400 - 1000 MHz; 6000 V/m, 1 - 18 GHz
    •  CW/SW @ 600 V/m, 400 MHz - 18 GHz

All HIRF tests are performed under full computer control, with flexibility to provide virtually any frequency step size, pulse duty cycle, or modulation type.

As an added benefit to our customers, Erik Borgstrom, EMC Operations Manager is an active member of the SAE AE4 HIRF / EUROCAE WG-14 Joint Working Group, which is in the process of revising the HIRF Users Guide, SAE ARP 5583.

Lightning/Transients

The flexibility of our lightning test system allows us to provide just about any waveform/transient desired.

Capabilities include Level 5 for all of the RTCA/DO-160E/F, Section 22 test waveforms and methods.

  •  Pin-injection testing
  •  Cable bundle testing
  •  Single-Stroke, Multiple Burst, Multiple Stroke at Level 1 to 5 (and higher)

In addition to RTCA/DO-160E/F, the new equipment also allows us to offer indirect lightning waveforms and test levels that meet the requirements of:

  •  Boeing D6-16050-4 & D6-16050-5
  •  Airbus ABD0100
  •  Many other military and commercial standards.

This capability compliments our High level HIRF and Power Quality capabilities to offer unparalleled coverage of your EMI needs for the Aerospace and Military industries.

Power Quality

Environ Laboratories offers Power Quality testing at very high voltage and high current levels, to comply with the newest requirements in RTCA/DO-160F, as well as the requirements from Boeing and Airbus.

The maximum voltage and current capabilities of our system are summarized below:

AC: DC:
  • 500 Volts (per phase)
  • 250 Amps (3 phase)
  • 750 Amps (1 phase)
  • 700 Volts
  • 1200 Amps

Our Power Quality test system is extremely flexible, providing us the capability to provide Single-Phase and Three-Phase AC power at virtually any frequency. In addition, for DC power quality testing, we can provide transients with extremely fast slew rates.

Our equipment also provides the capability for Power Quality testing in accordance with other commercial and military standards, such as:

  • MIL-STD-704
  • MIL-STD-1275
  • DOD-STD-1399
  • Boeing 787B3-0147
  • Airbus ABD0100.1.8
  • Airbus AMD 24
  • And others...
