Link to relevant study record(s)

Reference

Endpoint:

auto-ignition temperature (liquids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

18-Jul to 20-Jul-2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))

GLP compliance:

yes (incl. QA statement)

Remarks:

Certificat de conformite aux bonnes pratiques de laboratoire selon les directives 2004/9/CE et 2004/10/CE

Auto-ignition temperature:

567 °C

Atm. press.:

978 hPa

Preliminary test

The lowest auto-ignition temperature was found between 567 °C and 568 °C (corrected values) with a volume of 190 μL.

The main test will be conducted using this volume.

Main test (Summary)

Only the auto-ignition runs for each assay are summarised in the following table:

 

	Auto-ignition temperature (°C)		Auto- ignition	Maximal temperature of the air recorded in the center of the test flask after ignition (°C)		Atmospheric pressure (kPa)	Corrected Relative humidity (%)
Assay No.	Observed	Corrected	Lag (s)	Observed	Corrected
1	567	567	15	573	573	97.7	28
2	569	569	17	573	573	97.7	29
3	570	570	13	577	577	97.9	45
4	569	569	14	574	574	97.8	41
5	569	569	17	574	574	97.8	40

 

Conclusion

The auto-ignition temperature of the test item was 567 °C ± 3 °C (corrected temperature) at 985 kPa.

Conclusions:

No auto-ignition temperature was observed up to 567 °C at 978 hPa in a reliable study conducted according to an appropriate test protocol.
