Abrasion on the palm of a right hand, shortly after falling
Abrasions on elbow and lower arm, still healing. The elbow wound will produce a permanent scar.
In dermatology, an abrasion is superficial damage to the skin, generally not deeper than the epidermis. It is more superficial than an excoriation, although it can give mild bleeding. Mild abrasions do not scar, but deep abrasions may lead to the development of scarring tissue.

ASTM D968 measures the resistance of organic coatings to abrasion produced by abrasive falling onto coatings applied to a plane rigid surface, such as a metal or glass panel.
Method ASTM D 658 covers the determination of the resistance of organic coatings to abrasion produced by an air blast of abrasive on coatings applied to a plane, rigid surface, such as a metal or glass panel.
Abrasion resistance can be calculated in three ways: as loss in weight at a specified number of abrasion cycles, as loss in weight per cycle, or as number of cycles required to remove a unit amount of coating thickness.
