- JUSTIFICATION FOR DATA WAIVING
In accordance with Section 2 of REACH Annex XI, this study does not need to be conducted as testing is not technically possible. It is not possible to produce a powdered form of the substance suitable for testing as the powdered form is flammable.
Furthermore, it is not considered appropriate to test an extract following dissolution of the massive form in aqueous media as the substance is highly insoluble meaning there would be an insufficient concentration of dissolved metal ions in the extract solution to be tested.
