Product Description
Designed to evaluate resistance to scratching, a tool is fitted with an hemispherical end of 1mm (0.04”) diameter (standard), lowered gradually on to the surface of the sample and moved 60mm (2.36”). The sample width must be approximately 75mm (2.95 ).

Depending on the load applied, varying degrees of penetration of the tool into the coating are observed, from a superficial trace to total destruction. As the sample is pulled by hand, the tool lowers on to the sample, moves along it and gently rises up.
