ISO 4287

Definition

ISO 4287 is an international standard that defines the parameters for surface roughness measurement, focusing on the characteristics of surface textures. It establishes the terminology and methods for quantifying the roughness of surfaces, which is crucial for assessing how surfaces will interact in applications like friction and wear. This standard connects directly to how surfaces are analyzed and interpreted through various profilometry techniques, providing a framework for understanding surface quality.
