Scope

This SAE Recommended Practice describes a method for measuring roughness average (R_a) 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_a (? or ?in), and average peak count, PC (peaks per cm or peaks per inch) on cold-rolled steel sheet surfaces.
