36、nce The product is a granular material varying in colour from dark brown to dark grey to black, depending upon its origin. It consists of amorphous grains which can be rounded or sub-angular. The product shall be generally homogeneous and shall be visibly free of extraneous matter. 5.2 Particle size
37、 distribution The particle size distribution shall be described by either: a) effective size: (d10) with a maximum deviation of 5 %; uniformity coefficient: (U) less than 1,5 for Class 1 and Class 2 products with particles smaller than or equal to 1 mm; and less than 2,5 for Class 1 and Class 2 prod
38、ucts with particles greater than 1 mm. minimum size: (d1) with a limit deviation of 5 %; NOTE The particle size can decrease during transportation and handling. b) or, particle size range and mass fraction of oversize and undersize particles according to application. The maximum contents of oversize
39、 and undersize shall be a mass fraction of 10 % for application of the product in multimedia filters and a mass fraction of 5 % for use in single media filters. See A.2.3 for examples of available particle sizes that are used. Other values can be necessary for certain applications. 1)Chemical Abstra
