Product Code:SAE J911
Title:Surface Texture Measurement of Cold Rolled Sheet Steel
Issuing Committee:Sheet And Strip Steel Committee
Scope:This SAE Recommended Practice describes a method for measuring the surface texture of cold rolled, matte finish sheet steel with a roughness average (Ra) of 20-80 ? in. The method includes a system for equipment calibration and procedures for determining the arithmetical average surface roughness (Ra) and the average peak density (peaks per inch (ppi)) on sheet metal surfaces.
