In the absence of an analytical method meeting the minimum performance criteria set out in Part B of this schedule, the enforcing authority must ensure that monitoring is carried out using best available techniques not entailing excessive costs.

Measurement uncertainty must be estimated at the level of the parametric value, unless otherwise specified. Click to learn more.

Measurement uncertainties must be calculated and reported isso complete standard uncertainties, or as expanded standard uncertainties with an expansion factor of 1.

Most probable number method ISO Precision is a measure of random error and is usually expressed as the standard deviation within and between batches of the spread of results from the mean.
