39、e. 3.4 Chemical properties PolyDADMAC is a non-hazardous material and not intrinsically reactive. However, in common with many other organic compounds, a strong exothermic reaction will occur if it is brought into contact with strong acids or oxidizing agents. NOTE In dilute solution there can be a
40、reaction with, or destruction by, some of the disinfection and oxidizing agents used in water treatment. 4 Purity criteria 4.1 General This European Standard specifies the minimum purity requirements for polyDADMAC used for the treatment of water intended for human consumption. Limits are given for
41、impurities commonly present in the product. 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. DIN EN 1408:2008-04EN 1408:2008 (E) 10 NOTE Users of this product should
42、check the national regulations in order to clarify whether it is of appropriate purity for treatment of water intended for human consumption, taking into account raw water quality, required dosage and contents of other impurities and additives used in the product not stated in the product standard.
43、Limits have been given for impurities and chemical parameters where these are likely to be present in significant quantities from the current production process and raw materials. If the production process or raw materials lead to significant quantities of impurities, by-products or additives being
44、present, this shall be notified to the user. 4.2 Composition of commercial product The following requirements shall apply to polyDADMAC: there shall be no visible insoluble gel or extraneous matter; pH shall be in the range 4 to 7. 4.3 Impurities and main by-products DADMAC monomer: the product shal
45、l contain no more than 5 000 mg/kg active product. Based on the raw materials and manufacturing process (see A.1), there are no significant concentrations of additional reactants or by-products which are relevant to the application of these products in drinking water treatment. 4.4 Chemical paramete
46、rs Chemical parameters and indicator parameters as listed in EU Directive 98/83/EC (see 1) are not relevant to polyDADMAC 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 5.1.1 General
47、For sampling the recommendations given in ISO 3165 and ISO 6206 shall be followed. A representative sample of the liquid product, of sufficient mass, shall be obtained immediately after manufacture or from a newly opened container(s). The sample shall be clearly labelled with product name/code, batc
48、h number, type of container(s) sampled and date sampled. Reference samples shall be retained for the storage life of the product as claimed by the manufacturer/supplier. DIN EN 1408:2008-04EN 1408:2008 (E) 11 5.1.2 Sampling from drums and bottles 5.1.2.1 General 5.1.2.1.1 Mix the contents of the con
49、tainer 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. 5.1.2.1.2 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 5.1.2.1.3. 5.1.2.1.3 Examine the surface of the liquid. If there are signs of surface contamination, take samples from the s
