33、e Not applicable. 3.3.11 Physical hardness Not applicable. 3.4 Chemical properties Polyamines are non hazardous materials and not intrinsically reactive. However, in common with many other organic compounds, a strong exothermic reaction will occur if they are brought into contact with strong acid or
34、 strong 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 General This European Standard specifies the minimum purity requirements for polyamines used for the treatmen
35、t 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 notified to the user and when necessary to relevant authorities. 3)100 kPa
36、 = 1 bar. BS EN 1409:2008EN 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, taking into account raw water quality, required dosage and contents of other imp
37、urities 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 process and raw materials. If the production process or raw materials
38、 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 shall be no visible insoluble gel or extraneous matter; pH shall be in the rang

40、rials 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 parameters The product shall contain no more than 10 mg of epichlorohydrin (CAS
41、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 manufacturing process are free of them and they are not by-products of the manuf
42、acturing 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 obtained immediately after manufacture or from a newly opened container(s). The s
43、ample shall be clearly labelled with product BS EN 1409:2008EN 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 product as claimed by the manufacturer/supplier. 5.1.2 Sampling from drums and bottl
44、es 5.1.2.1 General 5.1.2.1.1 Mix the contents of the 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. 5.1.2.1.2 If the design of the container is such (for example, a narrow-necked
45、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 surface
46、as described in 5.1.2.2; otherwise, take samples as described in 5.1.2.3. 5.1.2.2 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
47、 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. 5.1.2.3 Bottom sampling Take a sample using an ope
48、n 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 trav
49、erses 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. 5.1.3 Sampling from tanks and tankers From each access point, take samples as follows: c) from the surface of the liquid, using a ladle as described in 5.1.2.2; d) from the bottom of the tank
