a) specified projection from outside of shell to extreme face of flange, ±13 mm (1/2 in.)
b) elevation and angular location, ±13 mm (1/2 in.)
c) flange tilt in any plane, measured across the flange diameter, ±13 mm (1/2 in.)
Help me understand how to check for projection from outside to face of flange, elevation, and angular location, and flange tilt
