^This!

In 30+ years of working in the fabrication industry, mostly in QC, I've had to prove over and over that the welding procedures and qualified welders I worked with met code and client requirements. This occurred on a daily basis and there wasn't any lee-way in what testing was required.

The testing was definitive in proving these procedures and welders could do what was required of them.

If I was required to provide a procedure that could withstand x force and x temperature, I had to provide charpy testing that proved it.

How hard is it to do an inert gas burn test to prove the reaction requires no oxygen?

How hard would it be to send samples to independent labs with a yellow sticky that says, "What am I?"?

(Not quite that simple but you get my point)

And would every lab choose the exact same methodology as Harrit et al?

If not, why?

Is it because the paper itself was only produced to pander to a specific target audience that wouldn't ask such questions?
