QC-621K can measure characteristics such as fastness, hardness and wear resistance of surface treatment. For example, it measures resistance to wear or fading for samples with painting, plating, coating and dyeing treatments. White cloth, sand bar, steel wool and eraser are common materials for abrasion.
The tester is powered by stepper motor and can perform abrasion at a regular speed, which is different from other abrasion testers moving in a simple harmonic motion with a limited test stroke. The tester can perform tests conforming to various standards under different conditions such as speed, stroke, specimen, abrasion head and load.
