If a Blueprint calls for ASME Y14.5 wouldn't this be the standard rules apply. How would I know if and when to apply ISO? I have yet to see anything on a blueprint stating this. The reason I bring this up is for the good old Profile callout. Before I make an argument, I want to cover all my resources. Customer already claims in an email that PC-DMIS is not capable of doing this. I and everyone on here already that's horse_S_H_I_T. But its Friday and I'm ready to P_I_S_S someone off
My ISO prints have ISO/DIN callouts all over the place. But in one corner does have ISO 8015.
ISO has "General Tolerances DIN 6930-m / ISO 2768 cL" and "Tolerancing ISO 8015" in one corner.
Below that is "Part Edges DIN ISO 13715"
And in the title block where it says whether it 1st or 3rd angle "ISO 10209-2: 1994-12".
It's kind of all over. If it's ISO, there are so many piecemeal standards that the print is just blanketed in ISO and/or DIN.
If it's a matter of the customer wanting the "surface profile" reported as 2x max deviation, well, I don't think I'd waste too much breath arguing whether or not that's ISO or ASME. If that's what they want to see, well, ASME doesn't really say "when reporting a single profile number, report max minus min (or 2x max)." ASME says the max and min are important, not some other constructed number. And, frankly, I'm glad that 99% of my surface profile callouts are done with single points and T values. There's no question there. It's either in tolerance at each point, or not.

Well the deal is that, I read this chain email, and there is a point where the CMM personal states " If there's one thing they taught us in level 2 PC-DMIS, was to always times your profile by 2." oh boy wet behind the ears, and everyone's buying it. So if a kid is misbehaving, do you shrug your shoulders at him, or do you tan his hide?
