Hello,
Well I should have started by saying welcome abord!
As to the metals those 2 listed was just samples I gave to get my point across, there's many others, like steel (as you stated) among others.
The standards you quoted, some are outdated and others have already been replaced. I.e.
> NOAA Oxygen specifications
They now state 23.5%/25%.
> OSHA Oxygen Specifications 1910.320
OSHA does not conduct testing and they used the 40% as a guideline to follow as a min. There is currently a major push to revise the OSHA standards to adopt the 23.5%/25% rule.
> US Coast Guard Oxygen Specifications
Basicaly same as the OSHA, they rely on the USN/NOAA/NASA standards, which now states 25%
> Title 46, 197.452 Oxygen Cleaning & 46 CFG 197.451
This is basicaly the OSHA/labor laws and they are rather dated, see above.
>US Navy Oxygen Specifications: US MIL-STD-777E (SH) Note K->6-4, Cat. K.6
Superceeded by MIL-STD-1330D.
Whether someone wishes to adopt the 23.5%, the 25% or the 40% rule for cleaning I urge each and everyone to not get wraped up in the percentage but instead get wraped up in the procedures and safety standards.
