Someone said they didn't like or accept the test that was used for the
penetrants. That a pin was not a thread. True a pin is not a threaded
rod, but to me his test is quite valid, but maybe not for what we are
thinking. His test was uniform, and does measure the abiliby of a
penatrant to penatrate. A force fit pin has a lot less clearence than
a thread. And it's ability to lubricate. Which we need to help lessen
the effort required to break something loose.
Now if you really want a test to be more realistic, repeat the same test
with one difference. Use bolts instead of pins. The aging process could
stay the same, and in fact seems quite good. Then you'd need something
like a socket on a breaker bar, and a spring scale, preferably with a
teltale, or sticking highest reading so you'd know how much torque was
exerted.
