Reference
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
16 November 2007 - 23 February 2008
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Key result
Relative self-ignition temperature:
326 °C
Conclusions:
The test substance temperature increased to > 400 °C (reaching a maximum of 406°C) at an oven temperature of 326 °C. This temperature (326°C) was therefore taken to be the self-ignition temperature for R507-2.

After the experiment, there was only a small amount of grey/black residue left in the cube. No test substance had been collected in the container placed below the cube.

In conclusion, R507-2 is self-ignitable at 326°C.
Executive summary:

In conclusion, R507-2 is self-ignitable at 326 °C.
