5.1 Tolerances.
5.1.1 Gates and risers.
a. Surfaces that require machining:
1. Flat or round surfaces, maximum protrusion 0.000 to 0.010 inch above adjacent surfaces in the same plane.
2. Irregular surfaces, maximum protrusion 0.000 to 0.030 inch above adjacent surfaces.
3. Intersection of planes, 0.25 inch fillet radius, maximum.
b. Unmachined surfaces. Maximum protrusion of 0.000 to 0.005 inch above surfaces in the same plane but not to exceed the drawing tolerance envelope.
5.1.2 Dimensional.
a. For all investment cast blades and vanes use table I.
TABLE I. Dimensional tolerances for blades and vanes.

Tolerance |
up to 0.999 1.000 to 1.999 2.000 to 3.999 4.000 to 5.999 6.000 to 11.999 12.000 and over |
+ 0.005 + 0.010 + 0.015 + 0.020 + 0.030 + 0.045 |
b. For all investment castings other than blades and vanes use table II.
c. Dimensions from cast surfaces to finished surfaces are subject to the tolerances specified in table II.
