Tolerance symbols and definitions → table
- 1) UP tolerances for 1:12 tapered bore → table
-
2)
Tolerance values have become half the values in accordance with the revised ISO standard (2014) because
SD is defined as perpendicularity of outer ring outside surface axis with respect to datum established from the outer ring face.
