Your read of the document is correct. As I recall, we did wrestle with the
language with respect to the 'weldability' supplement, and we went
back-and-forth a few times in an attempt to reach consensus.
I suggest you call our ASTM F16.02 Subcommittee Chairman, Fred Weingruber,
and ask him as well. He can provide some background, and perhaps based upon
your querry, prepare a ballot that would improve the clarity of the
