This includes revising existing, or proposing and preparing new standards. Geometrical product specifications (GPS) — ISO code system for tolerances on linear sizes — Part 1: Basis of tolerances, deviations and fits 1 Scope This part of ISO 286 establishes the ISO code system for tolerances to be used for linear sizes of features of the following types: a) cylinder; b) two parallel opposite surfaces. These standards provide guidance for metal casting linear dimension tolerances where no other requirements exist for form, fit or function (general tolerances). It provides a system of tolerances and deviations suitable for two types of feature: “cylinder” and “two. Item Bearing Subtype.
