    • Cat. 1 (General Grade + Grade 2

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 CSR Annex 1 for detailed MeClas printout(s) with the specified input concentrations and resulting classification. Please visit www. for more information about the tool.
