- JUSTIFICATION FOR DATA WAIVING
In accordance with Chapter R.7A - Endpoint Specific Guidance, Section R.7.1.10.3, inorganic oxides in which the inorganic element is in its highest possible oxidation state are incapable of further reaction with oxygen and can thus be designated as non-flammable. Erbium (III) oxide is an inorganic oxide in which the inorganic element, Erbium, is in its highest possible oxidation state, +3. Therefore, it has been deemed scientifically unjustified to conduct the flammability study required in section 7.10. Furthermore, due to the test material being designated as non-flammable under the grounds listed above, the substance is also considered to be non-pyrophoric and non-flammable on contact with water and it is considered justified to also waive those studies. For pyrophoricity and flammability in contact with water, this waiving is further supported by the absence of structural alerts and the experience from handling in which no ignition and/or liberation of flammable gases is observed when the substance is in contact with water or air.

Additional information
Justification for classification or non-classification
Dierbium trioxide does not require classification as a flammable substance, neither under DSD, nor under CLP or UN GHS.
