36、s dry, sand-like, free flowing black granules. The particles are coated with a black manganese dioxide coating. The product has a granular shape, dense crystalline structure and a rough texture. The product shall be generally homogeneous and shall be visibly free of extraneous matter. 5.2 Particle s
37、ize distribution The particle size distribution shall be determined on samples taken at the point of manufacture using the test method 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) effectiv
38、e size: (d10) 0,30 mm to 0,35 mm with a maximum deviation of 0,03 mm; 1) uniformity coefficient: (U) shall be less than 1,6; 2) minimum size: (d1) shall be at least 0,25 mm; 3) maximum size: shall not exceed 1,25 mm; or b) by particle size range and by mass fraction of oversize and undersize particl

Limits are given for impurities commonly pr
41、esent in the product. Depending on the raw material and the manufacturing process, other impurities may be present and, if so, the user, and when necessary the relevant authorities, shall be notified. Users of this product should check the national regulations in order to clarify whether it is of ap
42、propriate purity for treatment of water intended for human consumption, taking into account raw water quality, contents of other impurities and additives used in the product not stated in this product standard. Limits have been given for impurities and chemical parameters where these are likely to b
43、e present in significant quantities from the current production process and raw materials. If the production process or raw materials lead to the presence of significant amounts of impurities, by-products or additives being present, the user shall be notified. The composition of the commercial produ
44、ct shall conform to Table 1. Table 1 Composition of commercial product Parameters Limit in mass fraction % Manganese oxides (as Mn)a0,2 to 0,8 Mass loss at 150 C max. 6 Ignition loss at 650 C max. 8 aThe manganese in the product is present as a mixture of different oxides. NOTE 1 Acid-soluble materi
45、al is not a relevant parameter for this product, which is not stable to acids and which will react with hydrochloric acid releasing chlorine gas. After filling, washing and commissioning of a filter system producing drinking water, manganese greensand should not increase the concentrations of chemic
46、al parameters (see 1). NOTE 2 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
47、 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.
