Surface Roughness and Peak Count Measurement of Cold-Rolled Sheet Steel
This SAE Recommended Practice describes a method for measuring roughness average (R\da) and Peak count (PC) of the surface of cold-rolled steel sheet. The method includes a system for equipment configuration, calibration, and procedures for determining average surface roughness, R\da (\gm or \gmin), and average peak count, PC (peaks per cm or peaks per inch) on cold-rolled steel sheet surfaces.
