That's the old dip and look test. When I say old I mean OLD, it must go back
to the early 1960's at latest. I don't recall now if any MIL test would be
applicable but most likely one to look at would be MIL 883. I vaguely recall
J STD 003 might also be relevant. 
AS all it does is dip a test piece at 1" per second and dwell then withdraw
same rate after a few more seconds, you can easily replicate the machine
with a pair of tweezers and simply counting as you dip. Precision doesn't
really matter that much as whatever route you go it's still a subjective
eyeball test. The later TRI-Moore tester dating from the late 60's was
slightly better (where a test piece is skimmed across the top of a solder
pot to simulate a wave soldering machine) but that still requires a
subjective evaluation. You most likely know about the wetting balance which
gives an objective measurement.

As old standards never seem to die in the MIL zone I bet if you searched
Solderability tester you would find someone still supplying it.

Subject: [TN] Solderability Dip Testing Device

The link below describes an old school semi- automated dip device used for
solderability testing :

https://www.ipc.org/TM/2.4.12a.pdf

The original citation  for this device came from a  now obsolete  Military
soldering specification. 

Does anyone recall that mil spec document number?   I thought it might be in
Mil Spec 28809 but I don't see it there. 

To cut to the chase,...  I seem to recall that military specification even
mentioned a manufacturer. That is what I am ultimately looking for.

Any help would be appreciated. 

Thanks in advance
