Description

This Standard gives values of the limit deviations for commonly used tolerance class for holes and shafts in machined workpieces calculated from the information given in AS 1654.1.

Graphical representations of tolerance zones are given in the Annex.

Identical with and reproduced from ISO 286-2:1988.

Scope

This part of ISO 286 gives values of the limit deviations for commonly used tolerance classes (zones) for holes and shafts calculated from the information given in ISO 286. It covers values for the upper deviations ES (for holes) and es (for shafts), and the lower deviations EI (for holes) and ei (for shafts) (see figure 1).

Note - In the tables of limit deviations, the values for the upper deviation ES or es are shown above the values for the lower deviation EI or ei except for tolerance class JS and js which is symmetrical about the zero line.
