Details
Document Number: J911_199803
Revision Number:
Title
Surface Roughness and Peak Count Measurement of Cold-Rolled Sheet Steel
Scope
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 (μ or μin), and average peak count, PC (peaks per cm or peaks per inch) on cold-rolled steel sheet surfaces.
