Runway Friction Tester (RFT)

The Dynatest 6875 Runway Friction Tester is an accurate and repeatable, self-contained continuous friction measuring equipment (CFME) that provides coefficients of friction (Mu) on airport runways.

The 6875 is designed for both functional (maintenance) and operational testing to evaluate surface friction including changes due to weather contaminants and rubber contamination. Operational friction testing can be performed during such adverse weather as heavy rain, ice, slush or snow.

The 6875 is a fully instrumented pickup truck available in either two wheel or four wheel drive. It uses a Dynatest Two-Axis Force Transducer mounted on a retractable fifth wheel assembly.

The test assembly provides real time vertical load and horizontal tractive force measurements. The 6875 meets all the FAA and ICAO specifications for friction measuring devices and is listed in both the FAA AC 150/5320-12 approved device list and the ICAO Airport Services Manual.
