Water quality. Characterization of analytical methods. Guidelines for the selection of a representative matrix1 Scope This document specifies representative materials suitable for the determination of the performance characteristics, including uncertainty, during the initial assessment of a quantitative method, used in a laboratory, for physico chemical water analysis. This document focuses on five main types of water: waters intended for consumption (5. 2); natural waters (5. 3); waste waters (5. 4); marine waters (5. 5); recreational waters (5. 6). NOTE
