Rough surfaces cause rough results. If youre only interested in knowing roughly how hard a part is, a rough surface will work. But if youre inter-ested in accurate, consistent test re-sults, always test a shiny surface. Even though the Rockwell method begins its hardness measurement beneath the surface of the part, the inherent vari-
