Description

This Standard provides the bases for a system of tolerances and deviations suitable for plain workpieces, and fits between mating cylindrical features or fits between workpieces having features with parallel faces such as the fit between a key and a keyway. Annexes give the basic equations and rules for establishing the system, examples of the use of the system and equivalent terms used in the Standard in eight languages. Identical with and reproduced from ISO 286-1:1988.

Scope

Identical with and reproduced from ISO 286-1:1988

This part of ISO 286 gives the bases of the ISO system of limits and fits together with the calculated values of the standard tolerances and fundamental deviations. These values shall be taken as authoritative for the application of the system (see also clause A.l).

This part of ISO 286 also gives terms and definitions together with associated symbols.
