BS EN ISO 286-1:2010 Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes - Basis of tolerances, deviations and fits
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”.
