I was curious how Figure 11-21 on ASME Y14.5-2018 would be interpreted in ASME Y14.5-1994.
I believe the total width in this case at at given point is 60.0 +0.4/-0.8 for 2018. Is this correct and is it true for 1994?
Is the statement below from 2018 true for 1994?
11.4.3.1 When the Toleranced Feature Is a Nonsize
Datum Feature. At the datum feature, the distance to
the true profile is zero. Since the datum feature may
not pass through the datum plane, the tolerance on the
considered feature shall be as follows:
(a) For an equal bilateral profile tolerance, half of the
profile tolerance is available for variation of the datum
feature. See Figure 11-21.
(b) For a unilateral profile tolerance, the tolerance may
only be applied into the material of the feature.
