Is there a difference in the latest revisions between ISO & ASME, how the datums are called out, I understand they are becoming more closely aligned.? Having completed a GDT course last year I was informed that call-out axis as a datum is not correct. I'd ideally seek a list of all differences of the standards now.
Thanks

The annotation of ISO and ASME Datums has been identical since the release of the ASME 14.5M-1994 standard.
The current standard is ASME Y14.5-2009.
