Surface Texture, Roughness (Ra), Peak Count(Pc), and Mean Profile Spacing, (Rsm) Measurement of Metallic Coated and Uncoated Steel Sheet/Strip to be Formed and/or to be Painted
|Publication Date:||1 April 2017|
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
