Hardness, Abrasion and Washability Testing
In the field of coating technology the concept of hardness generally refers to scratch resistance. To call this hardness is not perhaps quite correct use of language but it has historically been used in this way and is well established. Fundamentally it concerns the properties of the coating material to withstand moved mechanical influences so as to leave no trace or evidence on the coating.
