- 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 ( ??)@ 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
