Results and discussion

Auto-ignition temperature (liquids / gases)
Auto-ignition temperature:
380 °C
Atm. press.:
ca. 1 013 hPa
Remarks on result:
other:
Relative self-ignition temperature (solids)
Relative self-ignition temperature:
380 °C
Remarks on result:
other:
Remarks:
at atm. press. of ca.1013.0 hPa

Any other information on results incl. tables

Self-ignition started at 380°C (given here as the self-ignition temperature). This high self-ignition temperature precludes a classification according to UN transport regulations (class 4.2).

The DTA (20 bar) showed weak self-heating starting at 250°C, accelerating at temperatures above 350°C.

Applicant's summary and conclusion

Conclusions:
The test item has a self-ignition temperature of 380°C and does not require classification according to UN transport regulations (class 4.2).
Executive summary:

The test substance has a self-ignition temperature of 380°C and does not require classification according to UN transport regulations (class 4.2).
