MeClas

The MeClas tool allows to classify complex inorganic materials like ores and concentrates, complex intermediates, alloys, UVCBs or waste, recognising the specific properties and assessment techniques for inorganics, using the most updated information on toxicity references and self-classifications available. The tool includes several tiers, aiming for a progressive refinement of the classification through recognition of speciation, specific mineral content and the availability of test data on the complex material in question. It allows to classify under EU CLP, GHS and US OSHA.
