Referenceopen allclose all
Beginning at about 408 °C the sample showed a weak exothermic reaction. However, the test substance does not undergo spontaneous combustion. A copy of the recorder trace is attached (see Graph of the Relative Spontaneous Ignition).
No exothermic effects were determined up to 410 °C.
Description of key information
not self-heating
Key value for chemical safety assessment
Additional information
The test substance (massive and granular form (MMAD: 991 µm) does not undergo spontaneous combustion. Niobium is classified as not undergoing spontaneous combustion when tested according to EC Test Procedure A 16.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
