Results and discussion
Relative self-ignition temperature (solids)open allclose all
- Relative self-ignition temperature:
- > 400 °C
- Remarks on result:
- other: layer assay
- Remarks:
- at atm. press. of other:likely atmospheric pressure (not indicated)
- Relative self-ignition temperature:
- > 500 °C
- Remarks on result:

Applicant's summary and conclusion
- Conclusions:
- Based on the results the test item does not need to be classified for flammability.
- Executive summary:
Yeast extract powder had no ability to self-ignite:
- as simple layer, after filtering at 200 µm: self-ignition temperature > 400°C
- as suspended dust, after vacuum drying: self-ignition temperature > 500°C
Pressure was not indicated but since the systems did not seem to be closed, it was likely atmospheric pressure.
