This article is based on new rules used in ISO GPS standards (year 2017). All rules important for creating of tolerancing model (as dimension, roughness and geometrical specifications) was harmonized and more clearly defined across standards. Article provides rules for the tolerancing of a tolerance zone pattern, i.e. a collection of tolerance zones constrained to each other with or without reference to a datum system which doesn’t lock all degrees of freedom, simultaneous requirement, combined zone etc. All rules shall respect the independency principle defined into ISO 8015. This article explains application of pattern specifications to specific components with detailed descriptions.
