scope:

This SAE Recommended Practice describes a method for measuring Roughness Average (Ra) and Peak Count (PC) and other variables of the surface of metallic coated and uncoated steel sheet/strip.

The method includes a system for equipment configuration, calibration, and procedures for determining average surface roughness, Ra ( μm), average peak count, PC (peaks per cm) and mean profile spacing, Rsm on metallic coated and uncoated steel sheet/strip surfaces.

This specification is based on metric measurements, English measurements are approximations only
