    individual measurements
6 Linearity of calibration graph
7 Linearization of data
8 Fitting the best straight line

10 Procedure when y is independent of x
11 Calculation of uncertainty
12 Systematic error limits and reporting procedure
13 Extrapolated values
14 Uncertainty in the use of the calibration graph for a
    single flowrate measurement

Covers methods for use in deriving the calibration curve for any method of measurement for flowrate in closed conduits or open channels and for the assessment of the uncertainty associated with such calibrations. Also covers methods for estimating the uncertainty arising in measurements obtained by means of the resulting graph and for calculating the uncertainty in the mean of a number of measurements of the same flowrate.
