Materials and methods
Test guideline
- Qualifier:
- no guideline available
- Guideline:
- other: Siemens DTA
- Deviations:
- not specified
- Principles of method if other than guideline:
- Flammability: powder-swell was formed onto a tile.
The substance was inflamed with a heated platin-conductor at one end.
DTA in closed cup with heating rate of 3K/min was tested to check thermic stability. Only glass cup was used. Additional the same test was done under 20 bar air pressure to check O2-effect onto the thermic stability of the product. - GLP compliance:
- not specified

Results and discussion
Auto-ignition temperature (liquids / gases)
- Auto-ignition temperature:
- > 270 °C
- Atm. press.:
- ca. 20 Bar
- Remarks on result:
- other: with O2 above melting point at approx. 270 °C first Oxidation reaction starts.
Relative self-ignition temperature (solids)
- Relative self-ignition temperature:
- > 270 °C
- Remarks on result:
- other: with O2 above melting point at approx. 270 °C first Oxidation reaction starts.
- Remarks:
- at atm. press. of ca.20.0 Bar
Applicant's summary and conclusion
- Conclusions:
- with O2 above melting point at approx. 270 °C first Oxidation reaction starts.
In closed glass cup without O2 at 280 - 270 °C a slight exothermic reaction of -50J/g was measured. A critical spontaneous heating could be bared.
Melting of the product avoids spread of fire and spread of glow-nest. Creation of glow-nest can be eliminated as an ignition of a dust explosion. - Executive summary:
