A limit within which agreement may be expected 95% of the time
between two test results obtained in different laboratories for the same
homogeneous sample of material.
Reproducibility is the variation that results when different conditions are
used to make the measurements of the same characteristic and is
represented by
reproducibility
.
Stability:
Stability is the consistency of performance
over time.
Stability can be evaluated using a control chart
and plotting measurements on the same part
over time.
