29、 Reference 2)Iron hydroxide oxide: 257-098-5. 4.2 Commercial form Iron (III) hydroxide oxide is a granular product consisting of irregularly shaped (non-moulded) particles; the product is available in different particle sizes. The water content is a mass fraction of up to 50 %. 5 Physical properties
30、 5.1 Appearance The product consists of black to brown granular material with particles of irregular shape. The product shall be generally homogeneous and shall be visibly free of extraneous matter. 5.2 Particle size distribution The particle size distribution shall be described by either: a) effect
31、ive size (d10)with a maximum deviation of 5 %; uniformity coefficient (U) less than 2,1; minimum size (d1) with a maximum deviation of 5 %. or b) particle size range and mass fraction of oversize and undersize particles; see A.2.2.1. The proportion of oversize plus undersize particles shall not exce
32、ed a mass fraction of 20 % and not more than a mass fraction of 10 % shall be undersized. NOTE 1 The particle size can decrease during transportation and handling. NOTE 2 Other values can be necessary for certain applications. 5.3 Density The bulk density (loose) shall be within 10 % of the value sp
33、ecified by the manufacturer or supplier. The bed density (backwashed and drained) should be in the range of 500 kg/m3to 1 800 kg/m3. 6 Chemical properties This European Standard specifies the minimum purity requirements for iron (III) hydroxide oxide used for the treatment of water intended for huma
34、n 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. 2) European Inventory of Existing Com

36、der to clarify whether it is of appropriate purity for treatment of water intended for human consumption, taking into account raw water quality, contents of other impurities and additives used in the products not stated in this product standard. Limits have been given for impurities and chemical par
37、ameters 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 present, this shall be notified to the user. After fil
38、ling, washing and commissioning of a filter system producing drinking water, iron (III) hydroxide oxide should not increase the concentrations of chemical parameters (see 1). NOTE Water-extractable substances, determined in accordance with the method for granular materials given in EN 12902, can be
39、used to estimate the leaching of the chemicals specified in EN 12902. 7 Specific properties The surface area shall be not less than 100 m2/g. 8 Test methods 8.1 Sampling Prepare the laboratory sample(s) required by the relevant procedures described in EN 12902. 8.2 Analysis 8.2.1 Particle size distr
40、ibution The particle size distribution shall be determined on samples taken at the point of manufacture in accordance with the method of test given EN 12902, using wet sieving. 8.2.2 Bulk density loose The bulk density loose shall be determined in accordance with EN 12902, without drying the sample,
41、 which could lead to a reduced volume. 8.2.3 Surface area The surface area shall be determined by the BET method, degassing at a maximum of 200 C, in accordance with ISO 9277. 9 Labelling, transportation and storage 9.1 Means of delivery Iron (III) hydroxide oxide shall be delivered in bulk, in semi
42、-bulk containers, big bags or in drums of plastics-lined cardboard, plastics or steel or suitable bags of various sizes. NOTE In case of dry iron (III) hydroxide oxide, cardboard drums without plastics-lining can be used. In order that the purity of the product is not affected, the means of delivery
43、 shall not have been used previously for any different product or it shall have been specially cleaned and prepared before use.
