ISO 21920-3:2021 PDF Download

An extensive framework for specifying surface texture using profile approaches is provided by the ISO 21920-3:2021 standard. It lays out the entire surface texture specification operator, ensuring uniformity and accuracy in the dissemination of surface texture requirements.

The standard strives to ensure that there is a shared understanding of how to specify surface texture utilizing profile methods across all parties involved in manufacturing and quality control operations. The standard fosters uniformity and clarity in the communication of surface texture requirements by offering a standardized set of specification operators.

A wide range of topics relating to surface texture specification are covered by ISO 21920-3:2021, including methods for assessing a surface's profile, metrics for quantifying surface texture traits, and guidelines for expressing surface texture specifications. It offers recommendations and best practices for choosing suitable specification operators depending on the intended use and desired surface texture properties.
