- Expiration date: 9 November 2006
- Storage condition: at room temperature, 10 to 30°C

Key result

Remarks on result:

no self-ignition observed up to the melting point

Prior to heating, the test sample was a white free flowing powder.

No exotherm is visible in the temperature/time chart trace of the experiment. The small negative deviation at approximately 130°C corresponds with the melting temperature. After heating, a residue was present in the holder at the bottom

of the furnace, suggesting that the test substance had melted during the test and solidified on cooling.

Conclusions:

On heating the test substance to 180°C, no self-ignition was observed.

Description of key information

From a key study (K1, Bates, 2002) according to EC method A.16, it could be derived that no self-ignition was oberved up to 180°C, which is above the melting temperature of the test substance.
