Reproducibility

In metrology, the term “reproducibility,” when reported in instrument specifications, refers to the closeness of agreement in results obtained from duplicate tests carried out under similar conditions of measurement. It is specified in terms of scale readings over a given period of time. It also represents a static characteristic of an instrument.

As with repeatability, the uncertainty is based on statistical measures. Manufacturer claims of instrument reproducibility must be based on multiple tests (replication) performed in different labs on a single unit or model of the instrument.
