HIRF Test

HIRF Test (High Density Radiating Areas)

At OLUROLAB, we have been providing services for customers in the aviation and other related industries for many years under electromagnetic compatibility tests. With our fully equipped electromagnetic testing facilities and the combined expertise of our team, we are developing a comprehensive testing program to identify regulatory challenges and meet your challenges.

HIRF Test

Of particular concern for avionics manufacturers, high-density radiating fields (HIRF) are any combination of electrical and magnetic interference strong enough to potentially affect the performance of a device close to it. HIRF is divided into three frequency bands, and each can affect aircraft electronics in different ways:

  • Low frequency electromagnetic emissions between 10 kHz and 50 MHz - Low frequency HIRF uses electrical components such as antenna skin, generates current in the body skin, but shows little internal penetration.
  • High frequency electromagnetic emissions from 100 MHz to 18/40 GHz - High frequency HIRF provides powerful field input into the body.
  • Medium frequency electromagnetic emissions between 30 MHz and 400 MHz - Medium frequency HIRF combines the effects of both LF and HF emissions, producing both antenna-like behavior and trunk penetration.

HIRF and Electromagnetic Tests

HIRF testing is a form of EMC testing that is applied to equipment exposed to extreme electromagnetic environments or critical mission equipment whose malfunctions can be dangerous to human safety. Concerns over the protection of these systems have increased in flight operations. Concern for the protection of electrical and electronic systems in aircraft has increased significantly in recent years for the following reasons:

  • Reduction of electromagnetic shielding provided by new composite materials.
  • Increased use of electrical and electronic systems to perform flight and landing functions.
  • Increased sensitivity of systems to HIRF due to increased bus and processor operating speeds, higher density integrated circuits and cards, and greater electronic equipment precision
  • Expansion of frequency usage over 1GHz.
  • Increased severity of the HIRF environment due to an increase in the number of RF transmitters.
  • HIRF requirements are applied to ensure that aircraft electrical and electronic systems can continue to operate safely without interruption, failure or failure.

EUROLAB HIRF Test

OLUROLAB test laboratories are fully equipped to provide HIRF and other electromagnetic interference tests for today's most demanding customers. We are the country's largest independent laboratory and standards-compliant organization, with a long history of needs for military contractors, aerospace manufacturers, and more. We make sure that you meet the requirements of various specifications containing HIRF certification, for example:

  • FAA HIRF Rule and Consultation Circular 20-158
  • RTCA / DO-160E / F: Category AL, All CW, SW and Pulse Test levels
  • Boeing Requirements: All CW, SW and Pulse test levels
  • Airbus Requirements: All CW, SW and Pulse test levels

HIRF certification generally involves measuring transfer functions to estimate the potential effects of electromagnetic interference (EMI) on an aircraft. In this we use a variety of tools and techniques to produce accurate tests that fully comply with all required specifications.

Reverberation Rooms

Our reverberation rooms and state-of-the-art amplifiers achieve more than DO-200 Category L levels from 18 MHz to 160GHz. Large available test volume chambers allow multiple LRU systems to be tested. With field densities that can reach peak areas of up to 15.000 V / m, these rooms can also be adapted to the driver and matched with a motor driver for rotating equipment.
