Description of key information
Reaction Mass of Lanthanum Phosphate and Cerium Phosphate and Terbium Phosphate is not highly flammable. Furthermore, no pyrophoric properties and flammability in contact with water is expected based on chemical structure and experience during manufacture and use.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
A GLP experimental study, according to EU method A.10 and scored as Klimisch 2, is selected as a key study and revealed that Reaction Mass of Lanthanum Phosphate and Cerium Phosphate and Terbium Phosphate is not considered as highly flammable. Due to the absence of structural alerts, it is highly unlikely that Reaction Mass of Lanthanum Phosphate and Cerium Phosphate and Terbium Phosphate is flammable in contact to water or in contact with air. Furthermore, under conditions where Reaction Mass of Lanthanum Phosphate and Cerium Phosphate and Terbium Phosphate is in contact with water or air, no ignition and/or liberation of flammable gases is observed.
Justification for classification or non-classification
The EU method A.10 is used to establish the classification with respect to flammable properties under DSD. In the case of a non flammable test item, it can be assume that the UN N.1 test used to classify under CLP would have led to the same conclusion. Indeed, the main differences between both tests are:
- The presence of a wetted zone during the UN N.1 test.
- A shorter period of observation of the combustion propagation during the preliminary screening assay of the UN N.1 test.
As a result, knowing the test item did not burn during the A.10 test, it can be expected that a similar behaviour would have been obtained under the slightly different experimental conditions applied during the UN N.1 test.
Based on the above information, Reaction Mass of Lanthanum Phosphate and Cerium Phosphate and Terbium Phosphate does not require a classification regarding its flammable properties, neither under DSD, nor under CLP or UN GHS.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
