ISO 2768-2 PERPENDICULARITY TOLERANCES TABLE


The general perpendicularity tolerances table according to ISO 2768-2. Dimensions mainly applies to the parts that are produced by material removal.


Perpendicularity tolerances for ranges of nominal lengths of the shoter side
Tolerance Class up to 100 over 100
up to 300
over 300
