This SAE Recommended Practice describes a method for measuring Roughness Average (Ra) 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, Ra (µm or µin), and average peak count, PC (peaks per cm or peaks per inch) on cold-rolled steel sheet surfaces.
