In 2003 the material information shifted between A 108 and A 29. A 108-99 has those GXXXX designations. In A 108-03 all those are gone. Maybe ASTM decided having the grade designations in both standards was redundant.

Actually, the way the example ordering information reads in A 108, they encourage you to use SAE numbers rather than grades of A 29 (even those are SAE numbers), but yet the text of A 108 says you want to refer back to A 29 for your composition. But I digress.

I went back to my oldest D1.1 (96) and it references A 108. As stated by ctacker, the forward states it was a correction made to ASTM reference. Was the correction due to the changes you reference? Was there another reason?

I assume it was. We had to make a similar change in our state specs. You can't refer to "ASTM A 108 Grade G10100" when no such thing exists any more. They haven't made this change in D1.5 yet but it's probably coming.
