Surface Roughness Standards ISO 25178 and ISO 4287 Overview

This document provides a detailed overview of surface roughness standards, focusing on ISO 25178 and ISO 4287, and explains how surface texture parameters like Sa, Str, Svk, and Sdr are used to quantify and manage product feel and functionality. It compares line roughness (profile method) with areal surface roughness (3D method), highlighting the advantages of ISO 25178 for both contact and non-contact evaluation.
