Guideline:

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

Deviations:

no

Qualifier:

according to guideline

Guideline:

other: DIN 51794

Deviations:

no

Qualifier:

according to guideline

Guideline:

other: IEC standard 79-4

Deviations:

GLP compliance:

yes

Auto-ignition temperature:

230 °C

Atm. press.:

ca. 1 002.1 - ca. 1 019.8 hPa

Remarks on result:

other: The lowest temperature at which ignition of the test substance occurred was 234°C

Preliminary study result:

Estimated auto ignition temperature was 250°C.

Main study result:

The result of the main study are shown in Table 2. Ignition of the test substance within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was <10°C.

The lowest temperature at which ignition of the test substance occurred was 234°C. This temperature was a multiple of 5°C and therefore given as the auto-ignition temperature of the test substance.

Table 2: Main study: auto-ignition temperature of the test substance

Conclusions:

An auto ignition temperature of 230°C at 1002.1 – 1019.8 hPa was determined for the substance in accordance with an appropriate test method and in compliance with GLP. The result is considered reliable.
