Changes and Additions to ASME Y14.5M

There are number of significant changes between each revision of the ANSI/ASME Y14.5M Dimensioning and Tolerancing Standard. It is difficult to grasp the scope of the changes by simply reviewing the standards themselves. ASME has provided lists of the principal changes and improvements in appendices of the recent standards. Although this is a useful listing, it requires users to flip back and forth through both standards to review these changes and improvements.
