- Version / remarks:
- (2008)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 51794: "Determining the Ignition Temperature of Petroleum Products" (2003)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: IEC 79-4: "Electrical Apparatus for Explosive Gas Atmospheres, Part 4, Method of Test for Ignition Temperature" (1975)
- Deviations:
- no
- GLP compliance:
- yes
- Auto-ignition temperature:
- 420 °C
- Atm. press.:
- 1 026.6 - 1 029.6 hPa
- Remarks on result:
- other: The reported auto-ignition temperature is the lowest auto-ignition temperature measured for the substance (see table below), rounded down to the nearest multiple of 5°C.
- Conclusions:
- In a GLP-compliant study in accordance with EC A.15, DIN 51794 and IEC 79-4, the auto-ignition temperature of the substance at 1027 – 1030 hPa has been determined as 420°C.
