Perpendicularity

[Sa-Ro]

Refer drawing.

I have mentioned perpendicularity wrt A.
Produced part is with in perp tol.

But the tol zone is not perp to drawing view.

In this case, part approved or not?

Perp or parallelism or angularity tol zone should be perpendicular to the drawing view specified or can be in any orientation (without deviating orientation to datum) to confirm the specified surface orientation?

Thank you

Sa-Ro,
In most cases, yours included, tolerance zones are not view-dependent and are only oriented to the referenced datums.
If the feature is perpendicular relative to datum A within up to 0.2, it passes the perp. requirement regardless of the slant in the shown direction.
If you care about both directions you could reference B as a secondary datum to constrain the rotational degree of freedom that allows the slant you depict.
I recall you use ASME Y15.5-2018. See fig. 9-4.

Also, in your top view (shown at bottom of your sketch), the width you give (10 to 11 mm) is not measured in that way. You are assuming that the width is related 90º to the depth measurement.
Instead, the dimension of 10 to 11 mm would be a straight-across measurement, normal to the surfaces that it's spanning across.
In the 2018 standard this idea is discussed in paragraph 5.8.3.
