GB/T 6060.1-1997 Focus casting surface roughness comparison sample. This standard specifies the production materials, processes and surface characteristics of the casting surface roughness comparison sample to ensure that the sample can truly reflect the casting surface conditions of different asperity grades. Detailed description of the type of sample and the corresponding asperity value range provides a visual reference for evaluating the casting surface roughness. When used, the asperity grade can be quickly and easily judged by comparing the actual casting surface with the sample. It is a practical tool for mass inspection and product surface mass control in the foundry industry.
