History of surface texture metrology until the latest ISO 25178 standard on areal surface texture.
Areal field parameters from ISO 25178-2, with amplitude parameters (Sa, Sq, etc.) and spatial and hybrid parameters (Sdr, Sal, etc.).
Areal functional parameters on bearing ratio, Sk parameters, functional indices and volume parameters, largely used in the automotive industry.
Areal feature parameters calculated by segmentation, that allows the characterization of specific structures.
Panorama of parameters defined in various standards for the evaluation of roughness and waviness profiles.
Introduction to the new standard that will modernize profilometry and that should replace all previous profile standards.
Introduction to the classical roughness parameters, in particular Ra, Rz or RSm, and their waviness and primary equivalent.
This standard is used in the automotive industry to caracterize profile motifs, close to functional requirements.
