DIN EN 12909:2013-01 EN 12909:2012 (E) 5 1 Scope This European Standard is applicable to anthracite used for treatment of water intended for human consumption. It describes the characteristics of ant
24、hracite and specifies the requirements and the corresponding test methods for anthracite. It gives information on its use 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 application. Fo
25、r dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The pro
28、duct has a granular or angular shape, amorphous structure and smooth texture. The product shall be generally homogeneous and shall be visibly free of extraneous matter. DIN EN 12909:2013-01 EN 12909:2012 (E) 6 5.2 Particle size distribution The particle size distribution shall be determined on sampl
29、es taken at the point of manufacture using the method of test given in EN 12902. NOTE 1 The particle size can decrease during transportation and handling. The particle size distribution shall be described by either: a) effective size: (d10) with a maximum deviation of 5 %; uniformity coefficient: (U
30、) which shall be less than 1,5; minimum size: (d1) with a maximum deviation of 5 %; or b) by particle size range and by mass of oversize and undersize particles according to application. The maximum contents of oversize and undersize shall be a mass fraction of 5 % for application of the product as
31、a filtration layer in multi media filters and a mass fraction of 10 % for use in single media filters. For use as a support layer, maximum mass fractions of oversize and undersize of 15 % are acceptable. See A.2.3 for examples of available particle sizes that are used. NOTE 2 Other values can be nec
32、essary for certain applications. 5.3 Density 5.3.1 Bulk density loose The bulk density loose shall be in the range of 650 kg/m3to 800 kg/m3.5.3.2 Bulk density packed The bulk density packed shall be in the range of 670 kg/m3to 820 kg/m3.6 Chemical properties This European Standard specifies the mini
33、mum purity requirements for anthracite 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 notified to th
34、e user and when necessary to relevant authorities. 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, contents of other impurities and additi
35、ves 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 current production process and raw materials. If the production process or raw materials lead to signifi
36、cant quantities of impurities, by-products or additives being present, this shall be notified to the user. The composition of the commercial product shall conform to Table 1. DIN EN 12909:2013-01 EN 12909:2012 (E) 7 Table 1 Composition of commercial product Parameter Mass fraction % C (water and ash
37、 free basis) min 90 Ash max 7 Volatile matter max 10 NOTE 1 These parameters do not influence filtration properties but give information about the source of anthracite. NOTE 2 Other potential components are given in A.2.1. After filling, washing and commissioning of a filter system producing drinkin
38、g water, anthracite should not increase the concentrations of chemical parameters (see 1). NOTE 3 Water extractable substances, determined in accordance with the method for granular materials given in EN 12902, can be used to estimate the leaching of the chemicals specified in EN 12902. 7 Test metho

DIN EN 12909:2013-01 EN 12909:2012 (E) 8 8 Labelling, transportation and storage 8.1 Means of delivery Anthracite shall be delivered in bags, semi-bulk containers, or bulk. In order that the
42、purity of the product is not affected, the means of delivery shall not have been used previously for any different product or it shall have been specially cleaned and prepared before use. 8.2 Labelling in accordance with the EU legislation 1)Anthracite is not listed within Annex VI of Regulation (EC
43、) No 1272/2008 at the date of publication of this European Standard. The legislation 2, and its amendments for the purposes of its adaptation to technical and scientific progress contains a list of substances classified by the EU. Substances not listed in this regulation should be classified on the
44、basis of their intrinsic properties according to the criteria in the regulation by the person responsible for the marketing of the substance. 8.3 Transportation regulations and labelling Anthracite is not a dangerous cargo. 8.4 Marking The marking shall include the following: name “Anthracite“, trad
45、e name and particle size range; net mass or the volume; name and the address of supplier and/or manufacturer; statement “this product conforms to EN 12909“. 8.5 Storage (long term stability) Anthracite can be stored for an unlimited period of time. 1) See 2.

46、Annex A (informative) General information on anthracite A.1 Origin A.1.1 Raw material Natural anthracite coal. A.1.2 Manufacturing process Anthracite is produced by mining, crushing, cleaning, drying and sieving. A.2 Typical properties A.2.1 Chemical composition The composition depends on the origin
47、. Typical limits are given as an example in Table A.1 (the main components are given in Clause 6). Table A.1 Chemical composition ParameterMass fraction % SiO2max 3 Fe2O3max 1Al2O3max 2 CaO max 1 K2O max 1 Na2O max 1Mineralogical and petrological analyses give additional information. A.2.2 Mechanica
48、l strength The mechanical strength of anthracite is high. Abrasion products consist of dust and small particles of material. They are formed during transportation, filling, and washing. Abrasion products are not completely removed by washing. The existing methods for determination of abrasion do not lead to exact results regarding behaviour of filter media during operation. They can be used only for comparison of different filter media. DIN EN 12909:2013-01 EN 12909:2
