"I would think that it is not necessary to start modifying hardware and perhaps invalidating warranties in the process of getting to the bottom of the fuse directionality issue. IMO the methodology I suggested earlier should suffice, if done in an honest and careful manner."
Huh? I’m not suggesting that anyone modify hardware or invalidate warranties or any such thing. I’m just saying that you can eliminate the variable of the fuse holder by eliminating it from the test. I’m referring to an independent third party tester. That would be an honest and careful manner, no? Or maybe you’re insinuating that any person who doesn’t get the results you’re looking for isn’t honest and careful, it’s hard to tell. The method you suggested earlier actually doesn’t suffice since some people will jump to the conclusion that it’s the fuse holder that’s directional, not the fuse itself.

Third party?

"And what recognized industry third party would that be?
Better yet. I am not disputing whether a fuse is directional or not. I believe many that have actually taken the time and tested it for themselves. BUT, with that said can you furnish anything that proves a fuse is directional? Not from a manufacture of audio grade fuses, but rather from an industry independent third party testing laboratory."
You say you believe many people have taken the time to test directionality. One assumes you’re referring to listening tests. The biggest skeptics of aftermarket fuses don’t even do that. Ah, the academic ivory tower.
As for independent third party tester it could be UL. I personally doubt UL would take the job. It could be someone else, some other organization or even individual. I actually don’t think measuring voltage drops or whatever across a fuse requires a rocket scientist. Maybe you can contact NASA or NIST or MIT and see if they are interested. Lol
"The HiFi Tuning fuse measurements that are provided in data sheets on their website were obtained by an independent third party tester. You probably didn’t realize that."
There it is again, third party.
It gets better!

Geoffkait: The HiFi Tuning fuse measurements that are provided in data sheets on their website were obtained by an independent third party tester.
to which Jea48 responded,
"For Fuse directionality?"
For fuse directionality and other stuff. Even fuse directionality for AC circuits.
On the question!
