Key result

Auto-ignition temperature:

ca. 405 °C

Atm. press.:

>= 989 - <= 1 001 hPa

Preliminary test

The estimated auto-ignition temperature was 435°C.

Main study

The results of the main study on the determination of the auto-ignition temperature of the test item are given in Table 5.

Ignition of the test item 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. According to the guidelines, no further testing was required.

The lowest temperature at which ignition of the test item occurred was 406°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 405°C.

Conclusions:

Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of Glyceryl triacetyl ricinoleate.
The self ignition temperature of the test substance was found to be 405 °C, under the conditions of the test.
The atmospheric pressure was 989 and 1001 hPa.

Executive summary:

In this guideline (EU A.15) study, conducted with GLP certification, the self ignition temperature of the test substance was found to be 405 °C. The atmospheric pressure was 989 and 1001 hPa. Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of Glyceryl triacetyl ricinoleate.
