This is performance that will be met by 80% of
instruments with 80% confidence, for ambient
temperatures in the range of 18 °C to 28 °C,

include the effects of the uncertainties of external
calibration references and aging over the course of
the published calibration interval. These values are
determined from qualification testing and are not
warranted or tested in the performance verification.
