Measurement system uncertainties
In accordance with ISO 80601-2-70:2015 the measurement uncertainty of the manufacturer's test equipment is:
For measures of flow
For measures of static pressure
For measures of dynamic pressure
For measures of volume (< 100 mL)
For measures of volume (≥ 100 mL)
For measures of time
Note: ISO 80601-2-70:2015 stated accuracies and test results provided in this manual for these items already include the
relevant measurement uncertainty from the table above.
