Water quality. Estimation of measurement uncertainty based on validation and quality control data Ingestion-build-266356 water-based media or an alternative1 Scope 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. NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the principles described in ISO IEC Guide 98 3. In this
