Results and discussion

Auto-ignition temperature (liquids / gases)
Auto-ignition temperature:
ca. 420 °C
Remarks on result:
other: Depending on the specific situation, a safety margin should be used.

Any other information on results incl. tables

Depending on the specific situation, a safety margin should be used. It is assumed that surface apperatuur, which can make contact with an explosive vapor-air mixture, not greater than 80% of the ignition temperature in ° C.

For the mixture, this offered a maximum surface temperature of 336 ° C

Applicant's summary and conclusion

Conclusions:
Ignition temperature
For the sample presented the self-ignition temperature of 420° C.
This substance is on this basis classified in group T2 temperature according to "NPR 7910 Gevarenzone-indeling met betrekking tot gasontploffing
gevaar."
The self-ignition temperature is not a material constant, but depends on the geometry and volume of the space in which this substance is determined.
Magnification has a volume reduction of the ignition temperature effect.

Executive summary:

Both the relative self-ignition for solids and the auto-ignition temperature for liquids are not used

directly for classification and labelling. However, they can be used in the chemical safety

assessment in considering risks associated with processing the substance. Information from the UN

tests can be used for transport purposes; however, this is outside of the context of this guide.
