C3 Wet Traction Trailer

1) Overview

• The test equipment is a device for measuring the wet traction coefficient on wet surfaces of TBR tires.
• The test equipment consists of a towing vehicle with a complete instrumentation system and a test trailer, which utilizes a two-axis converter to provide real-time vertical load and horizontal traction measurements.
• This test equipment is equipped with its own spray system to measure the coefficient of friction on dry and wet roads during tire test driving.

2) Compliance with Industry Standards

• ECE R117 : Uniform Provisions Concerning the Approval of Tire with Regard to Rolling Sound Emissions and to Adhesion on Wet Surfaces and/or to Rolling Resistance
• ISO 15222 : Truck and bus tire - Method for measuring relative wet grip performance - Loaded new tire
