COMMON QUESTIONS

Before you specify

Does this page provide numerical tolerances?

No. Use the limits in the specified edition of the governing standard and approved drawings.

Does nominal size mean an exact measured size?

No. Nominal designations and dimensional acceptance limits serve different purposes.

Can I request tighter tolerances?

Include the proposed limits, measurement method and critical features for feasibility review.

What happens if a measurement is outside the agreed limit?

It requires review against the agreed acceptance and deviation process; it should not be assumed acceptable.
