I am pleased to announce that the ASME Y14.45 standard for Measurement Data Reporting has finally been published! As a founding member and vice-chair of the development subcommittee, this is a very proud moment.
The primary objective of Y14.45 is to provide standardized definitions and formats for reporting GD&T measurement data. This makes it extremely relevant to CMM inspection and I'm optimistic that Y14.45 will become a must-have document for CMM professionals. I expect that the standard will reinforce a lot of what you know already, and provide guidance on some more complex issues that have historically been left open to interpretation. We made a real effort to address difficult topics such as profile reporting, MMC and bonus tolerance, surface interpretation, patterns, composite FCF's, and optimization.
I also expect that Y14.45 will be a great aid for understanding the GD&T functionality in PC-DMIS. I know from committee colleagues that Hexagon has invested a lot in making PC-DMIS follow the GD&T standards more closely.
Just as importantly, I believe that Y14.45 will be a great help (and eye-opener) for those not directly involved in dimensional metrology. It will help them to appreciate how difficult and complex GD&T gets when you need to to go beyond Pass/Fail and actually calculate numbers from the measurements!
Y14.45 is available now in PDF format, and the hard copy version is schedule for Jan 26. Here is a link for ordering:

I'm expecting that the Y14.45 standard will generate a lot of questions and comments and I'm looking forward to the dialogue. Feel free to fire away or contact me privately.
