I am running a GR&R on leak test equipment. I have two leak test equipment that test parts exactly the same
or should be testing them the same. My question is when running a GR&R on these two machines how much of a deviation from one machine to the other should I expect.
The most that I have seen so far running stdev on excel was 7.35 and the least was 1.48 stdev. If any one could shed a little light on this it would be appreciated.
