40、s, a strong exothermic reaction will occur if it is brought into contact in the dry state with a strong acid or oxidizing agent. NOTE In dilute solution, there can be a reaction with, or destruction by, some of the disinfection and oxidizing agents used in water treatment. 4 Purity criteria 4.1 Gene
41、ral This European Standard specifies the minimum purity requirements for cationic polyacrylamides used for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the product. Depending on the raw material and the manufacturing process other impurit
42、ies may be present and, if so, this shall be notified to the user and when necessary to relevant authorities. NOTE Users of this product should check the national regulations in order to clarify whether it is of appropriate purity for treatment of water intended for human consumption, taking into ac
43、count raw water quality, required dosage and contents of other impurities and additives used in the product not stated in the product standard. Limits have been given for impurities and chemical parameters where these are likely to be present in significant quantities from the current production pro
44、cess and raw materials. If the production process or raw materials lead to significant quantities of impurities, by-products or additives being present, this shall be notified to the user. 4.2 Composition of commercial product The cationic polyacrylamide shall be free of any visible extraneous matte
45、r. NOTE Various parameters can be checked as part of assessment of product quality (see 5.2.2). DIN EN 1410:2008-04 EN 1410:2008 (E) 10 4.3 Impurities and main by-products Based on the raw materials and manufacturing process (see A.1), there are no significant concentrations of additional reactants
46、or by-products which are relevant to the application of these products in drinking water treatment. 4.4 Chemical parameters The product shall contain no more than 200 mg of acrylamide monomer per kilogram of product. NOTE Other chemical parameters and indicator parameters as listed in EU Directive 9
47、8/83/EC (see 1) are not relevant to polyacrylamides because the raw materials used in the manufacturing process are free of them and they are not by-products of the manufacturing process. 5 Test methods 5.1 Sampling Sampling shall be in accordance with ISO 8213 and the recommendations given in ISO 3
48、165 and ISO 6206 shall be followed. A representative sample of the solid product, of sufficient mass, shall be obtained immediately after manufacture or from a newly opened package(s). The sample shall be clearly labelled with product name/code, batch number, type of container(s) sampled and date sa
49、mpled. Reference samples shall be retained for the storage life of the product as claimed by the manufacturer/supplier. 5.2 Analyses 5.2.1 General Unless otherwise specified, all reagents shall be of recognized analytical grade. The water used shall conform to grade 2 specified in EN ISO 3696. 5.2.2 Main product If additional requirements are agreed between the customer and the manufacturer/supplier, the latter shall provide the necessary test methods, if requested, so that the customer can carry out his own quality checks.
