N m3 of a gas
N m3 of a gas
(OP)
Is there a standard accepted definition for "N m3" when speaking about gases? I see conflicting information with some sources using 0 C as the reference temperature whereas others use 20 C.
Is there any widely accepted definition of the term?

This is why it is so important to state your standard conditions whenever you issue a calculation or specification. If someone issues a document to you make sure that you know what standard they are using.

Even if not universally accepted definitions, any idea if the industrial gas majors have agreed upon a definition? I was trying to look up the Praxair / Linde websites but did not find any guidance. In case it matters, this is for Hydrogen.

But one cylinder it doesn't.
Somewhere in the middle is usually a good point and the 15C / 60F and 1.01325 bara / 14.696 psia is usually my start point if no one has defined it and the odd decimal point isn't that important.
