The Dynamic Friction Tester (D.F. Tester)

The Dynamic Friction Tester (D.F. Tester) is compliant with the rigorous ASTM standard E-1911-98. Measuring the slip resistance of road surfaces can be challenging, but the D.F. Tester is easy to handle, yields extremely precise measurements, can be used in narrow places, and can measure the slip resistance of road surfaces in a single measurement. Critically, it has built-in functions to measure the relationship between friction and speed - the correlation coefficient is outputted directly. It is used by a wide range of institutions including research institutes, road companies, universities, automobile manufacturers, and tire manufacturers.

Features

  • Time required for measurement is short and handling is easy. Used by connecting to a PC.

  • It is easy to carry and can be transported by van, pickup truck, or SUV.

  • Can be used simply by connecting to the vehicle power supply

  • Correlation between speed and friction coefficient is directly output.

  • Replacing the rubber slider is easy. The rubber slider uses materials that comply with ASTM E501 and E524 tires.

  • Includes a thickness gauge that allows to see at a glance when to replace the rubber slider.

  • Uses 12V DC power supply.

  • It is possible to calculate IFI (International Friction Index) by combining with CT meter.

Appropriate Road Surfaces

  • Paved highways, general roads, runways

  • Paved pedestrian roads and bicycle roads

  • Panel

  • Tile
