"Statistical studies shall be conducted to analyze the variation present in the results of each type of inspection, measuring, and test equipment system identified in the control plan."
I work with molten aluminum. (Die casting) We have melting and holding furnaces in which we monitor the temperature (~ 1200 - 1300 f) and have ranges called out on the control plan. They are all digital readouts and are calibrated. I received a non-conformance for not having GRR's on them. How do I do a GRR on a piece of process monitoring equipment which I cannot remove from the system and have no way of knowing a true "known" value for to try to do something in place?
Thanks in advance!
