The device comp
46、rises a polishing station and a unit for measuring the friction. The polishing station, which is continuously supplied with a mixture of water and quartz powder, contains three polishing rollers that can be lowered and that move across the test surface at a predefined loading force. In the friction
47、measuring unit, a rotating measuring head is lowered onto the test surface while water is being added. The measuring head is fitted with three sliding blocks and can be declutched electronically. The moment generated by the contact between the rubber sliders and the surface is continuously measured
48、and recorded until the measuring head comes to a standstill. The friction is subsequently calculated from the moment measured at 60 km/h. 5 Equipment 5.1 Test device 5.1.1 General The test device consists of a unit to polish the sample, a specimen clamping system and a unit for measuring its friction. 5.1.2 Polishing
