The new ASME Y14.5-2009 standard on dimensioning and tolerancing reflects a culmination of effort extending over 15 years. It is a revision of the ASME Y14.5M-1994 standard. The M in the title of the old standard recognized the fact that it was metric compatible and was deemed no longer necessary, so it was dropped. There are many changes, improvements, and enhancements in this new standard from the earlier 1994 standard. That said, it is impossible to address the implications of all the changes in a short article. But prospective users can benefit from general guide to some of the new changes. The new ASME Y14.5-2009 standard is progressing forward and reflects the state of the art in industry today. In general, the major change to the standard is that users will find it much easier to use and understand, but the fundamental geometric concepts have not changed.
