Scope

This specification is applicable to the calibration of surface roughness comparison samples. It includes surface roughness comparison samples processed by methods such as grinding, turning, boring, milling, inserting, planing, EDM, shot (spray) peening, sandblasting, grinding, filing, and polishing, as well as samples copied by electroforming using these samples as master models (motherboards), and "surface roughness standard parts" selected from batch-produced components.
