RCA Szpengjie PJ-7-IBB-CC test machine principle:

  • This RCA abrasion tester uses a special paper tape as the friction medium; and place a fixed load on the friction head.
  • The friction head continuously applies force to the surface of the sample through a roller of fixed diameter; and a paper tape powered by a fixed speed motor; until it is visible that the substrate can reach a specific level of wear; and the wear resistance of the sample is assessed by the number of revolutions of the motor displayed by the counter.
