The GB/T 1031-2009 standard specifies the parameters and numerical series for evaluating the surface roughness of industrial products, which are suitable for the evaluation of the surface structure of products. The standard adopts the midline system (contour method) for the evaluation of surface roughness. The recommended asperity parameters include the arithmetic average deviation Ra of the contour and the maximum height Rz of the contour, covering the needs of surface roughness assessment from micro to large scales. The standard provides a standardized technical basis for ensuring the surface mass of industrial products.
