Describes methods for the estimation of measurement uncertainty of chemical and physicochemical methods in single laboratories based on validation data and analytical quality control results obtained within the field of water analysis.

This International Standard specifies methods for the estimation of measurement uncertainty of chemical and physicochemical methods in single laboratories based on validation data and analytical quality control results obtained within the field of water analysis.

NOTE1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the principles described in ISO/IEC Guide98-3.

In this International Standard, the quantification of measurement uncertainty relies on performance characteristics of a measurement procedure obtained from validation and the results of internal and external quality control.

NOTE2 The approaches specified in this International Standard are mainly based on QUAM^[11], NEN7779^[8], Nordtest TR 537^[10], and Eurolab TR 1^[9].

NOTE3 This International Standard only addresses the evaluation of measurement uncertainty for results obtained from quantitative measurement procedures. The uncertainties associated with results obtained from qualitative procedures are not considered.
