<p>This International Standard specifies methods for the estimation of measurement uncertainty of chemical and</p>
<p>physicochemical methods in single laboratories based on validation data and analytical quality control results</p>
<p>obtained within the field of water analysis.</p>
<p>NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the</p>
<p>principles described in ISO/IEC Guide 98-3.</p>
<p>In this International Standard, the quantification of measurement uncertainty relies on performance</p>
<p>characteristics of a measurement procedure obtained from validation and the results of internal and external</p>
<p>quality control.</p>
<p>NOTE 2 The approaches specified in this International Standard are mainly based on QUAM[11], NEN 7779[8], Nordtest</p>
<p>TR 537[10], and Eurolab TR 1[9].</p>
<p>NOTE 3 This International Standard only addresses the evaluation of measurement uncertainty for results obtained</p>
<p>from quantitative measurement procedures. The uncertainties associated with results obtained from qualitative procedures</p>
<p>are not considered.</p>
