Abstract

ISO 14405-2:2011 illustrates the use of geometrical tolerancing for dimensions that are not linear sizes to avoid the ambiguity that the use of ± tolerances on these dimensions causes. Both linear and angular dimensions, except size of features of size, are covered.

Dimensional tolerancing can be indicated by ± tolerancing or geometrical tolerancing.

The ambiguity caused by using ± tolerances for dimensions other than linear sizes is explained in an informative annex.
