General This European Standard specifies the minimum purity requirements for aluminium based coagulants used for the treatment of water for swimming pools. Limits are given for impurities commonly present in the products. Depending on the raw material and the manufacturing process other impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities. SIST EN 15031:2006
Composition of commercial product The concentration of active matter (aluminium ion content) in the manufactured product expressed in grams per kilogram of product shall be within ± 3 % of the manufacturer's declared values. NOTE The concentration of water-soluble aluminium in commercial products varies. Typical values are given in Table 1. SIST EN 15031:2006
Polyaluminium chloride hydroxide sulfateb) Solid 30 to 254 a) The commercial products vary in the proportions of chloride and sulfate ions. The relative basicity of these products, expressed as the mole ratio OH/3Al, shall be less than or equal to 0,35. b) The commercial products vary in the proportions of chloride and sulfate ions. The relative basicity of these products, expressed as the mole ratio OH/3Al, shall be greater than 0,35. 4.3
Impurities and main by-products Impurities derived from the manufacturing or extraction processes include insoluble matter, trace metals and organic compounds. If iron is present, the products shall conform to the requirements specified in Table 2. Table 2-Limits of impurities Product Grade Impurity Limit g/kg of Al Iron free Iron (Fe) max. 1,60 Low iron Iron (Fe) max. 1,60
Iron (Fe) max. 0,8 Sodium aluminate
Insoluble matter (solid product) max. 8 Note: The value quoted for iron is both iron (II) and iron (III).
Chemical parameters The content of arsenic, cadmium, chromium, mercury, nickel, lead, antimony and selenium for each type of product shall conform to the requirements specified in EN 878, EN 881, EN 882 and EN 883. NOTE Cyanide (CN- ) is usually not relevant because of the acidity of the products. Pesticides and polycyclic aromatic hydrocarbons are not relevant since the raw materials used in the manufacturing process are free of them. 5 Test methods 5.1
Sampling 5.1.1 Solid Observe the general rules of ISO 3165 and take into account ISO 6206. Prepare the laboratory sample(s) required by the relevant procedure described in ISO 8213. 5.1.2
Liquid 5.1.2.1 Sampling from drums and bottles 5.1.2.1.1 General 5.1.2.1.1.1 Mix the contents each container to be sampled by shaking the container, by rolling it or by rocking it from side to side, taking care not to damage the container or spill any of the liquid. 5.1.2.1.1.2 If the design of the container is such (for example, a narrow-necked bottle) that it is impracticable to use a sampling implement, take a sample by pouring after the contents have been thoroughly mixed. Otherwise, proceed as described in 5.1.2.1.1.3. 5.1.2.1.1.3 Examine the surface of the liquid. If there are signs of surface contamination, take samples from the surface as described in 5.1.2.1.2; otherwise, take samples as described in 5.1.2.1.3. 5.1.2.1.2
Surface sampling Take a sample using a suitable ladle. Lower the ladle into the liquid until the rim is just below the surface, so that the surface layer runs into it. Withdraw the ladle just before it fills completely and allow any liquid adhering to the ladle to drain off. If necessary, repeat this operation so that, when the other selected containers have been sampled in a similar manner, the total volume of sample required for subsequent analysis is obtained. 5.1.2.1.3
Bottom sampling Take a sample using an open sampling tube, or a bottom-valve sampling tube, suited to the size of container and the viscosity of the liquid. When using an open sampling tube, close it at the top and then lower the bottom end to the bottom of the container. Open the tube and move it rapidly so that the bottom of the tube traverses the bottom of the container before the tube is filled. Close the tube, withdraw it from the container and allow any liquid adhering to the outside of the tube to drain off. When using a bottom-valve sampling tube, close the valve before lowering the tube into the container and then proceed in a similar manner to that when using an open sampling tube. SIST EN 15031:2006
Labelling - Transportation - Storage 6.1
Means of delivery Solids: the products shall be delivered in suitable packages, paper or plastics bags
Liquids: the products shall be delivered in containers of corrosion-resistant materials suitable for the purpose. NOTE The manufacturer can provide advice on suitable materials. In order that the purity of the products is not affected, the means of delivery shall not have been used previously for any different product or it shall have been specially cleaned and prepared before use. 6.2
Risk and safety labelling in accordance with the EU directives 1 The following labelling requirements shall apply to the following aluminium based coagulants at the date of the publication of this European Standard: Aluminium sulfate: a) solids, hydrated forms: symbols and indications of danger: Xi: Irritant. nature of special risks attributed to dangerous
