What pipe sizes are excluded from charpy impact testing?

What pipe sizes are excluded from charpy impact testing?

What pipe sizes are excluded from charpy impact testing?

(OP)
ASME B31.3 Table 323.2.2 Note 6 excludes impact testing when the maximum obtainable specimen has a width along the notch of less than 0.098 inch. So if you were trying to test a circumferential weld in an existing pipe joint, what pipe sizes/schedules are excluded from impact testing because the specimen width is too small?

Obviously, all the pipe size/schedule combinations with a thickness of 0.098" and smaller would be excluded, but there are still some pipe sizes with a thickness greater than 0.098" that you wouldn't be able to obtain the minimum sample size from.

I could draw different pipe sizes to scale and see if the minimum specimen fits in the pipe, but I don't have the resources for this. I've tried to figure out the trig for this, but haven't had much luck.

Any help would be greatly appreciated!
