25、by this European Standard: a) this European Standard provides no information as to whether the products may be used without restriction in any of the Member States of the EU or EFTA; b) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulation
26、s concerning the use and/or the characteristics of these products remain in force. Conformity with this European Standard does not confer or imply acceptance or approval of the products in any of the Member States of the EU or EFTA. The use of the products covered by this European Standard is subjec
27、t to regulation or control by National Authorities. DIN EN 15041:2014-06 EN 15041:2014 (E) 5 1 Scope This European Standard is applicable to polyphosphates used as antiscalants for membranes for treatment of water intended for human consumption. It describes the characteristics and specifies the req
28、uirements and the corresponding analytical methods for polyphosphates. It gives information on their use as antiscalants for membranes in water treatment. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its ap

34、he minimum purity requirements for polyphosphates used as antiscalants for membranes for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the products. Depending on the raw material and the manufacturing process other impurities may be presen
35、t and, if so, this shall be notified to the user and when necessary to relevant authorities. DIN EN 15041:2014-06 EN 15041:2006 (E) 6 Users of these products should check the national regulations in order to clarify whether it is of appropriate purity for treatment of water intended for human consum
36、ption, taking into account raw water quality, required dosage, contents of other impurities and additives used in the products not stated in this product standard. Limits have been given for impurities and chemical parameters where these are likely to be present in significant quantities from the cu
37、rrent production 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 products shall conform to the following requireme
38、nts on a dry mass basis: phosphate content expressed as P2O5: mass fraction of (64 to 69) %; sodium content expressed as Na2O: mass fraction of (29 to 34,5) %. 4.3 Impurities and main by-products The products shall conform to the requirements specified in Table 1. Table 1 Impurities Impurity Limit m
39、g/kg of dry product Sulfate (SO42-) max. 500 Fluoride (F-) max. 10 4.4 Chemical parameters 4.4.1 Generals Content of various chemical parameters depends on the origin of the raw materials, most of these elements are present only as traces. The content of antimony, arsenic, cadmium, chromium, cyanide
40、s, lead, mercury, nickel and selenium shall conform to the requirements specified in Table 2 of EN 1212:2005. When preparing the products for analysis, it is important to ensure that the chemical parameters are effectively dissolved. The concentration of the solution should be sufficient to permit a
41、dequate sensitivity in analysis of the chemical parameters and appropriate steps should be taken to compensate for any matrix interference caused by the concentration of the products. 4.4.2 Determination of antimony (Sb), arsenic (As), cadmium (Cd), chromium (Cr), cyanide (CN), lead (Pb), mercury (H
42、g), nickel (Ni) and selenium (Se) 4.4.2.1 Principle The elements antimony, arsenic, cadmium, chromium, lead, mercury, nickel and selenium are determined by atomic absorption spectrometry. Cyanide is determined by molecular absorption spectrometry. 4.4.2.2 Reagents 4.4.2.2.1 General All reagents shal
43、l be of a recognized analytical grade and the water used shall conform to grade 3 specified in EN ISO 3696. 4.4.2.2.2 Hydrochloric acid, concentrated density = 1,42 g/ml. DIN EN 15041:2014-06 EN 15041:2014 (E) 7 4.4.2.3 Procedure 4.4.2.3.1 Test portion Weigh, to the nearest 0,001 g, 2,5 g (m) from t
44、he laboratory sample into a 100 ml one - mark volumetric flask. 4.4.2.3.2 Test solution Add 20 ml of water and 2 ml of the hydrochloric acid (4.4.2.2.2), dissolve and make up to the mark with water and mix. 4.4.2.3.3 Determination Determine the content of chemical parameters in the test solution (4.
45、4.2.3.2) in accordance with the following methods : Ni and Pb: in accordance with ISO 8288:1986, method A; Cd: in accordance with EN ISO 5961; CN-: in accordance with ISO 6703-1; Cr: in accordance with ISO 9174; As: in accordance with EN ISO 11969; Se: in accordance with ISO 9965; Sb: in accordance
46、with EN ISO 11885; Hg: in accordance with EN 1483. These methods provide an interim result (y) expressed in mg/l, which needs to be converted to give the final concentration according to the equation in 4.4.2.3.4. 4.4.2.3.4 Expression of results From the interim result (y) determined (see 4.4.2.3.3)
47、, the content, w3, of each element in the laboratory sample, expressed in mg/kg of dry antiscalant products is given by the following equation (1). mVyw =3(1) y is the interim result (4.4.2.3.3) ; V is the volume, expressed in ml, of the test solution (4.4.2.3.2) (= 100 ml) ; m is the mass, expresse
48、d in g, of the test portion. NOTE Pesticides and polycyclic aromatic hydrocarbons are not relevant in polyphosphates since the raw material used in the manufacturing process are free of them. 5 Test methods The sampling and the analytical methods are those described in EN 1212.
