NettetMohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness. To give numerical … Nettet8. jan. 2009 · In addition, the amount of time required for testing often prevents 100% testing of testable smaller parts.
