DIN EN 12915-1:2009-07 EN 12915-1:2009 (E) 5 1 Scope This part of EN 12915 is applicable to virgin granular activated carbon used for treatment of water intended for human consumption. It describes the characteristics of virgin
27、 granular activated carbon and specifies the requirements and the corresponding test methods for virgin granular activated carbon. It gives information on its use in water treatment. 2 Normative references The following referenced documents are indispensable for the application of this document. For

33、 (see 5.2). The product can be either shaped (moulded/extruded) or irregular (non-moulded), and is available in many grades, differing in adsorption characteristics, hardness, porosity, granulometry, shape and purity. 5 Physical properties 5.1 Appearance The commercial product consists of black, por
34、ous granules of irregular shape or, for moulded or extruded products, in forms such as uniform cylinders, pellets or spheres. 5.2 Particle size distribution 5.2.1 General The particle size distribution shall be determined on samples taken at the point of manufacture. The particle size distribution s
35、hall be within the manufacturers stated tolerance. NOTE 1 Different applications can require different particle size ranges. NOTE 2 The particle size can decrease during transportation and handling. 5.2.2 Irregular product The particle size distribution shall be described by either: a) effective siz
36、e: (d10) with a permitted tolerance of 5 %; uniformity coefficient: (U) shall be less than 2,1; minimum size: (d1) with a permitted tolerance of 5 %; or: b) by particle size range and by mass of oversize and undersize particles according to application: the content of oversize plus undersize shall n
37、ot exceed a mass fraction of 15 % and not more than a mass fraction of 5 % shall be undersize. NOTE Other values can be necessary for certain applications. 1) Chemical Abstracts Service Registry Number. 2) European Inventory of Existing Commercial Chemical Substances.

38、-1:2009 (E) 7 5.2.3 Moulded/extruded product Not more than a mass fraction of 3 % shall pass a test sieve with an aperture size as close as possible to 0,75 times the nominal particle diameter. 5.3 Wettability The wettability shall be greater than a mass fraction of 99 %. 5.4 Bulk density packed The
39、 bulk density packed shall be greater than or equal to 180 kg/m3. 5.5 Mechanical strength The ball-pan hardness shall be greater than 75. NOTE Products with a lower hardness are suitable for certain applications. 6 Chemical properties 6.1 General Granular activated carbon is manufactured by controll
40、ed oxidation (by means of steam or chemicals) from carbonaceous raw materials including coconut, wood, peat or coal. The raw materials shall be stated by the manufacturer. High internal porosity results in adsorptive properties and, depending on the raw material and the manufacturing process, it can
41、 have acid or basic properties. It is a reducing agent with catalytic properties. Activated carbon can react with oxidants to form carbon dioxide. The carbon content of the commercial product does not affect adsorption characteristics. 6.2 Purity criteria 6.2.1 General This European Standard specifi
42、es the minimum purity requirements for virgin granular activated carbon 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
43、 so, this shall be notified to the user and when necessary to relevant authorities. 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, c
44、ontents of other impurities and additives used in the products 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 pro
45、cess or raw materials lead to significant quantities of impurities, by-products or additives being present, this shall be notified to the user. 6.2.2 Impurities and main by-products The product shall conform to the requirements specified in Table 1.
