Manganese oxide: 215-202-6. 4.2 Commercial form Manganese greensand is a granular product available in only one particle size range. 5 Physical properties 5.1 Appearance The product comprises 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 size 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) effective 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 particles. The maximum permitted mass fractions of oversize and undersize are 5 %. NOTE 2 Other values might be necessary for certain applications.
