Check the AIAG MSA manual (I think it's Section 3, but maybe not) for methods of doing "destructive" MSA. (It's classified as destructive because the operators can't measure exactly the same thing each time.) It's Sunday, so I don't have any reference materials at hand, but I'll check this thread again tomorrow.cpine said:Anyone out there have an example of performing GR&R on a torque wrench.
I have some ideas however I'm not sure that they are valid.
As always, thank you in advance for your time and efforts.

"Destructive," in this sense, doesn't mean that the parts get destroyed. It just means that the analysis must proceed as though the parts were getting destroyed, because the same measurement can't be made twice, as it can be when measuring a static part with calipers, for example.cpine said:
I thought of Nested ANOVA and if I were doing destructive testing, typically I would test the part to failure. With a torque wrench that would'nt be the case.
I must be missing an important part of the equation any help would be
greatly appreciated.
