Scope
In this part of ISO 13909, formulae are developed which link the variables that contribute to overall
sampling precision. Methods are described for estimating overall precision and for deriving values for
primary increment variance which can be used to modify the sampling scheme to change the precision.
Methods for checking the variance of sample preparation and testing are also described.

Subjects

Coals (73.040) Solid fuels (75.160.10)
