AGMA 236.04 (pre 1961) shows Commercial Class 4 as:
T to T composite = .0007
Total Composite = .0015
Dudley shows Commerical class 4 to be comparable to
AGMA 390.01 class 9.
T to T composite = .0007
Total Composite = .0014
For your Pitch Dia and pitch, these numbers are the same in AGMA 390.03
I don't have 390.01, so would someone like to make a general comparison between .01 and .03? Are the differences in fine pitch minimal?
