Hello guys,
I have a really hard trouble making an analysis of my leak tester
We put the pipe plugged into the device (leak tester)with the opposite side blocked, then 150 psi air pressure fill the interior of pipe in order to verify any possible leak.
Once this device has completed the test, It displays a leak value which It should not be greater than the leak value specified in the print. If the value is greater, the part has failed because It has a leak.
Logically, this is not a replicable test, because same part never will show same values. We can not control the value, we can only control if the part is going to leak or not by checking all joints where It could be a leak. That is the most important thing here.
The problem is that a normal capability study does not represent anything here since we do not control the distribution of the data and I do not care if I have a CPK 1.33 in this case.
Someone recommended me a Gage R&R study Nested. I have already done that in Minitab but I can not find how that can help this.
Does anybody of you guys know something about how to conduct a kind of capability or Gage R&R Study for this type of situations? I really need some help.
Thanks in advance.
