However, in common with many other organic compounds, a strong exothermic re

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 General This European Standard specifie
40、s the minimum purity requirements for polyamines 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 impurities may be present and, if so, this shall be noti
41、fied to the user and when necessary to relevant authorities. 3)100 kPa = 1 bar. DIN EN 1409:2008-04 EN 1409:2008 (E) 9 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, takin
42、g into account 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 produ
43、ction process 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 following requirements shall apply to polyamines: there shal
44、l be no visible insoluble gel or extraneous matter; pH shall be in the range 4 to 7. 4.3 Impurities and main by-products The product shall conform to the requirements specified in Table 1.

45、ol 40 1,3-Dichloro-2-propanol 40 2,3-Dichloro-1-propanBased 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 param
46、eters The product shall contain no more than 10 mg of epichlorohydrin (CAS Number 106-89-8) per kilogram of active ingredient. NOTE Other chemical parameters and indicator parameters as listed in EU Directive 98/83/EC (see 1) are not relevant to polyamines because the raw materials used in the manuf
47、acturing 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 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 obtain
48、ed immediately after manufacture or from a newly opened container(s). The sample shall be clearly labelled with product DIN EN 1409:2008-04 EN 1409:2008 (E) 10 name/code, batch number, type of container(s) sampled and date sampled. Reference samples shall be retained for the storage life of the prod
