This International Standard specifies the characteristics of specimens of cast metallic surfaces which are intended for tactile and visual comparison with workpiece surfaces produced by similar casting methods and which have been cleaned by an appropriate treatment, for example shot biasting, grit biasting, or tumbling.
It is complementary to ISO 2632/1, Roughness comparison specimens — Part I : Turned, ground, bored, milled, shaped and planed, and to ISO 2632/11, Roughness comparison specimens — Part II : Spark-eroded, shot biasted and grit biasted, and polished.
