In my view, Harry Buttler's variation of the 'Yosemite' Bowline is superior.

Try this :

The 'testing' you refer to would likely be done by an enthusiast/hobbyist tester.
It is highly unlikely that a professional test lab would fund such a test.
...
Most enthusiast/hobbyist testers work in isolation using improvised test rigs.
While that is not 'bad' per se, it may not meet the rigor of professional test labs.
Why not undertake your own testing and report your results in the knot test section of this forum?
As for "rigor", YMMV : rigor in some senses amounts
to little more than superfluous nonsense --precise
measurements of a dubious quality, say!
Whereas some quick'n'dirty backyard testing can show
aspects of the knot well enough, nevermind having
some precise force value ascribed to it.
(I'm seeing now a bit of worry re the Butler YoBowl :
i.e., that the 2nd-made collar with the final tail tucking
can shift position vis-a-vis the main collar. So, take care
in dressing and do set it!)
