Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Version / remarks:
EU-Method A.16, of 30 May 2008 published on 31 May 2008, “Relative Self-Ignition
Temperature for Solids“
Deviations:
yes
Remarks:
The heating rate slightly deviated from the value stated in the guideline of 0.5 °C/min (0.59 °C/min). This is considered as uncritical as a nominal heating rate of 0.5 °C/min was adjusted at the instrument and only a minimal deviation was observed.
GLP compliance:
yes (incl. QA statement)

Applicant's summary and conclusion

Conclusions:
No increase in the temperature of the sample in comparison to that of the oven could be
detected; also no signs of ignition could be observed.
The test item 1.4-bis(isopropylamino)anthraquinone is considered as showing no self-ignition up to a temperature of 400°C under the test conditions.
No observations were made which might cause doubts concerning the validity of the study
outcome.
