 Organization: ISO Publication Date: 15 April 2010 Status: active Page Count: 46 ICS Code (Limits and fits): 17.040.10
##### 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.

It defines the basic concepts and the related terminology for this code system. It provides a standardized selection of tolerance classes for general purposes from amongst the numerous possibilities.

Additionally, it defines the basic terminology for fits between two features of size without constraints of orientation and location and explains the principles of "basic hole" and "basic shaft".
