4.1 Sensitivity
4.2 Identification of sources of errors
4.3 Combination of uncertainties
5. Presentation of results
Section two. Examples
6. Notation
7. Example of flow-rate measurement in circular pipes
7.1 General calculations
7.2 Detailed numerical example
7.3 Simplified numerical example
8. Example of open channel measurement
8.1 The formula for volume flow in open channel
8.2 The overall uncertainty of the flow determination
8.3 Numerical example
Annexes
A. Tests for outliers
B. Student's t distribution
C. Uncertainty in variables for which the values are
     derived from independent experiments
D. Combination of uncertainties

Calculations required in order to arrive at a statistical estimate of the interval within which the true flowrate may be expected to lie. The calculations are so presented as to be applicable to measurement in both closed and open ducts.
