by particle size range and by mass fraction of oversize and undersize particles. The maximum permitted mass fractions of oversize and undersize are 5 %. NOTE 2 Other values can be necessary for certain applications. 5.3 Density (bulk density loose) The bulk density loose shall be at least 1 300 kg/m3.

The manganese in the product is present as a mixture of different oxides. NOTE 2 Acid-soluble material is not a relevant parameter for this product which is not stable to acids and which will react with hydrochloric acid releasing chlorine gas. NOTE 3 After filling, washing and commissioning of a filter system producing drinking water, manganese greensand should not increase the concentrations of chemical parameters (see [1]). NOTE 4 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 Specific properties The oxidation capacity of manganese greensand (regenerated form), expressed as grams of Mn per litre of packed product, shall be at least 0,7 g/l. 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 distribution The particle size distribution shall be determined in accordance with EN 12902.

… (1) where X1 is the measured value. 8.2.4 Ignition loss at 650 °C 8.2.4.1 Principle Heating the sample to constant mass at 650 °C. It is assumed that water, including chemically bound water, is the only material present in the manganese greensand that is volatile at this temperature. At 650 °C the loss of water is practically complete. 8.2.4.2 Apparatus Ordinary laboratory apparatus and glassware together with the following. 8.2.4.2.1 Muffle furnace, capable of being controlled at (650 ± 25) °C. 8.2.4.2.2 High temperature metal or ceramic crucible with lid. 8.2.4.2.3 Desiccator. 8.2.4.2.4 Analytical balance, having an accuracy of ± 0,1 mg. 8.2.4.3 Procedure Ignite the crucible and the lid (8.2.4.2.2) in the muffle furnace at (650 ± 25) °C for 1 h. Place the crucible and the lid in the desiccator, cool to room temperature and weigh to the nearest 0,1 mg; note the mass m0. Place a 5 g to 10 g sample of manganese greensand into the pre-ignited crucible. Close the crucible and weigh immediately to the nearest 0,5 mg (m1). Remove the lid and place the crucible and lid in the muffle furnace at (650 ± 25) °C and leave for 3 h. Place the crucible in the desiccator, cover it with the lid and allow to cool to room temperature. When cool, weigh to the nearest 0,5 mg (m2). SIST EN 12911:2006
