ISO 4287 – Roughness parameters
Definition: ISO 4287 defines roughness parameters for profile-based surface measurements. It describes parameters such as Ra, Rz or Rt and their mathematical determination. The standard is the basis of tactile roughness measurement.
Practical relevance: ISO 4287 specifies terms and calculation rules for profile parameters. In combination with ISO 16610, filters are applied. The standard is widely used in mechanical engineering and manufacturing.
