The MECLAS tool allows classifying complex inorganic materials like ores and concentrates, complex intermediates, alloys or UVCBs, recognizing the specific properties and assessment techniques for inorganics, using the most updated information on toxicity references and self classifications available. Watch our MeClas video tutorial.
MeClas is built on a limited number of simple and basic principles:
- A tiered and inorganic specific approach allowing refinement in accordance with the following (not necessarily sequential) steps: elemental concentrations - speciation data - mineralogical evidence - release tool correction (if relevant) and correction based on test data on the complex material
- A core block including the ecotoxicity and toxicity reference values (ERVs/TRVs) and CLP, UN-GHS and OSHA hazard ID rulings forming the base of the MeClas tool
- An open building block structure
- Enabling the inclusion of specific side modules if relevant (e.g. for Ores and Concentrates, for Transport Classification, additional reference lists (e.g. Japan), alloys, etc.)
- Confidentiality assurance for proprietary information
- Equal participation and sharing rights
- All ERVs/TRVs data holders/providers are treated equally
- All full license holders participate in the MeClas Steering Committee
MeClas is governed by the following rules. All license holders of the tool shall agree with these principles when buying license rights to the MeClas tool:
- MeClas follows classification guidance and implements it accordingly to the legal ruling and provided technical guidance (ECHA, UN). For the EU, MeClas will not deviate from the proposed CLP guidance unless ECHA agreed with the proposed deviations approach.
- The MeClas tool will be adapted to the classification ruling when needed.
- MeClas classifies and ranks ERV/TRV data according to quality and following a strict procedure. New higher quality information overrules older or lower quality info after assessment by the quality control committee.
- ERVs/TRVs are never made public unless the Consortia provides explicit written agreement in doing so.
- All Consortia and Company specific RCS are stored on (a protected part of) the MeClas server allowing any change to the classification system, ERV/TRV to be conducted automatically and on an immediate basis.
You must register in order to access the MeClas tool and all supporting information. A short description of the Terms of conditions can be downloaded. The manual gives an idea on the basic functionalities of MeClas.
New MeClas video intro and video tutorial and Eurometaux guidance on the classification of inorganic UVCB substances for human health hazards is now published.
