Scrub test - micro-scratch resistance
The rub resistance of a component is the relative change in gloss as a percentage of the initial gloss level. A gloss measurement is carried out on the component in the unchanged state.
Then the component is rubbed with a micro abrasive grain attached to a type C friction pin.
Afterwards, the gloss is measured in the rubbed area and the abrasion resistance is determined.
