Good quality study with result derived on basis of the classification outcome (mixture toxicity rules) from a conservative, worst-case sample of the substance (max. of max for As, Cd, Co,Pb, Ni, Sb, and max. of typicals for other elements) across industry as defined in IUCLID section 1.2/4.27 for all grades, using mineralogical information from the representative sample. 

See IUCLID section 13 or CSR Annex 1 for detailed MeClas printout(s) with the specified input concentrations and resulting classification. Please visit www. meclas.eu for more information about the tool.
