- Experimental Starting Date: 28 May 2015 Experimental Completion Date: 29 May 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and the study was conducted under GLP conditions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Deviations:
- no
- GLP compliance:
- yes
- Key result

- 416 °C
- Atm. press.:
- 99.9 - 100.9 kPa
- Remarks on result:
- other:
- Conclusions:
- The test item has been determined to have an auto-ignition temperature of 416 ± 5 °C. The auto-ignition of the test item did not appear to be volume dependant.
- Executive summary:
The determination was carried out using a procedure* designed to be compatible with Method A15 Auto-Ignition Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.
* Based on Anon (1987) Electrical Apparatus for Explosive Gas Atmospheres, Part 4: Method of Test for Ignition Temperature,IEC Publications79-4, P1-19.
Conclusion
The test item has been determined to have an auto-ignition temperature of 416 ± 5 °C. The auto-ignition of the test item did not appear to be volume dependant.
