Hello, web searches are failing me, I must be looking for the wrong terms as usually fittings dimensions are easily accessible.

I am trying to figure out where to find the specifications for 1.5inch tube fittings (like seen in P-traps). Specifically the wall thickness requirements and thread specifications.

MPT threads are easy to find and ASTM codes specifies what I needed for DWV piping but I don't even know what to call these cheap tube fittings under the sink in order to look them up.
 
So that's what tube fittings are. I really didn't know. I just assumed they were those flimsy looking drain fittings.?????
Didn't notice any actual dimensions in that publication.
