The product can be either shaped (moulded/extruded) orirregular (non-moulded), and is available in many grades, differing in adsorption characteristics, hardness, porosity,granulometry, shape and purity.5 Physical properties5.1 AppearanceThe commercial product consists of black, porous granules of irregular shape or, for moulded or extruded products,in forms such as uniform cylinders, pellets or spheres.5.2 Particle size distribution5.2.1 GeneralThe particle size distribution shall be determined on samples taken at the point of manufacture. The particle sizedistribution shall be within the manufacturer’s stated tolerance.NOTE 1Different applications can require different particle size ranges.NOTE 2The particle size can decrease during transportation and handling.5.2.2 Irregular productThe particle size distribution shall be described by either:a) effective size: (d10)
with a permitted tolerance of
5 %;uniformity coefficient: (U)
shall be less than 2,1;minimum size: (d1) with a permitted tolerance of

The raw materials shall be stated by themanufacturer.High internal porosity results in adsorptive properties and, depending on the raw material and the manufacturingprocess, it can have acid or basic properties. It is a reducing agent with catalytic properties. Activated carbon canreact with oxidants to form carbon dioxide.The carbon content of the commercial product does not affect adsorption characteristics.6.2 Purity criteria6.2.1 GeneralThis European Standard specifies the minimum purity requirements for virgin granular activated carbon used forthe treatment of water intended for human consumption. Limits are given for impurities commonly present in theproduct. 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.NOTEUsers of this product should satisfy themselves that it is of appropriate purity for treatment of water intended forhuman consumption, taking into account raw water quality, required dosage, contents of other impurities and additives used inthe products not stated in the product standard, and other relevant factors.Limits have been given for impurities and water-extractable substances where these are likely to be present insignificant quantities from the current production process and raw materials. If a change in the production processor raw materials leads to significant quantities of other impurities or by products being present, this shall be notifiedto the user.6.2.2 Impurities and main by-productsThe product shall conform to the requirements specified in Table 1.SIST EN 12915-1:2003
