But I am not aware of any acceptance criteria defined on the basis of this percentage. In the third edition, the acceptance for both Linearity and Bias is based on t-tests and confidence interval calculations. %Linearity concept is dropped.
NettetA gage linearity and bias study determines whether your gage is measuring accurately. The study assesses linearity (how accurate your measurements are through the expected range of measurements) and bias (how well your measurements compare … NettetLinearity Study: → Select 5 – 8 parts that can be measured at different operating ranges of the measurement system. → Determine reference value for each part using layout inspection. → Use one appraiser to measure parts. → Take 10 – 12 repeated readings on each part. → Calculate part’s Bias and plot it against the references.
