MSA 3rd Edition question
Hello,
I first want to say this is a great forum with a lot of helpful info. I appreciate the service!
The question I have is: We just went through our QS audit and the auditor was questioning what we knew about the K values. with regard to GR&R. In his questioning he asked us why they change in the 3rd edition. I had no reply. Of course he wasn't looking for trouble just trying to see if it made sense to anyone else.
I understand that the K values are based upon the 5.15 @ 99%/ d2. However in the 3rd edition it is now based upon a smaller area under the curve. (Can't remember the exact number right now.) So can anyone tell me what's the deal? It looks like they got a little lenient on us or maybe I am just missing something.
Thanks for any assistance anyone can give.
