If the Total Gage R&R contribution in the %Study Var column (% Tolerance, %Process) is:

· Less than 10% - the measurement system is acceptable.

· Between 10% and 30% - the measurement system is acceptable depending on the application, the cost of the measuring device, cost of repair, or other factors.

· Greater than 30% - the measurement system is unacceptable and should be improved.



If you are looking at the %Contribution column, the corresponding standards are:

· Less than 1% - the measurement system is acceptable.

· Between 1% and 9% - the measurement system is acceptable depending on the application, the cost of the measuring device, cost of repair, or other factors.

· Greater than 9% - the measurement system is unacceptable and should be improved.
