18、) BSI BS EN 15216:2007 EN 15216:2007 (E) 5 1 Scope This European standard specifies a method for the determination of total dissolved solids (TDS) in water and eluates, provided they are not volatile under the conditions specified or that they do not release water molecules from hydration. It applie
19、s to water and eluates containing more than 200 mg/l of total dissolved solids. Samples with lower amounts of dissolved solids can be analyzed by repetition of the drying step. 2 Terms and definitions For the purposes of this document, the following term and definition applies. 2.1 total dissolved s
20、olids TDS TDS mass of dissolved constituents per unit volume of water remaining after a specified filtering and drying process NOTE TDS is expressed in milligrams per litre. 3 Principle The test sample is filtered and then dried in a dish to a constant mass in an oven at (105 3) C. 4 Sample storage
21、and preparation During storage, the laboratory sample may be subject to changes which are liable to influence the analysis result. If storage is necessary, samples shall be kept at (4 2) C. NOTE Freezing should be avoided due to risk of formation of precipitation. It is recommended to carry out the
22、test immediately after sampling of the water sample or preparation of the eluate. 5 Equipment 5.1 Drying system thermostatically controlled and capable of maintaining a temperature of (105 3) C; e.g. drying oven, infrared system. 5.2 Desiccator with an active drying agent such as silica gel. 5.3 Ana
23、lytical balance with an accuracy of 1 mg or better. 5.4 Membrane filter (porosity of 0,45 m). 5.5 Filtration apparatus. 5.6 Evaporation dish or crucible. Temperature tolerant laboratory vessel withstanding 105 C. Suitable materials are glass, ceramic, porcelain, aluminium and other materials inert t
