Wear / Abrasion resistance is the ability of the surface to resist loss of surface from rubbing or scraping/plucking actions that dislodge surface particles. In typical warehouse or distribution centres, conditions are relatively benign. Neoprene truck tyres do not cause scraping or plucking actions and in many cases, the tyres have a polishing effect rather than a wearing effect. Hard-wheeled pallet trucks can be aggressive on joints but there is little evidence of them causing direct wear on the floor surface.
Most loss of surface appears to be caused by scraping actions, typically from nails protruding from pallets that are pushed or dragged around. Dirty dusty floors can suffer wear when the dust is ground into the surface by rubber tired forklift trucks, a scenario that is more commonly in industrial buildings. In extreme cases such as waste transfer stations, the action of front loader buckets is very aggressive.

Wear resistance can be tested as per the main standard BS 8204, BS EN
13813 which says to follow BS EN 13892-4, Methods of test for screed
materials. Determination of wear resistance-BCA.

BCA stands for British Cement Association, the machine, simulates a
wearing mechanism by the use of three hardened-steel wheels mounted on a
revolving plate. The plate revolves at a set speed for a set time under a
prescribed load. The resultant annulus of wear is measured at eight points and
the average depth of wear is reported to the nearest 0.01 mm.
Let see the testing process:
As per BS EN 8204 part 2, abrasion results can be considered as:
Classification of abrasion resistance and limiting depths of wear for
the abrasion test: recommendations for concrete bases, directly finished (DF)
only, as wearing surfaces:
Classification of abrasion resistance and limiting depths of wear for
the abrasion test: Recommendations for concrete bases upgraded by dry
shake/sprinkle finishes and for applied wearing screeds (WS)
