Key result
Auto-ignition temperature:
220 °C
Atm. press.:
>= 1 020 - <= 1 025 hPa

Preliminary Test

The estimated auto-ignition temperature was 265°C.

Main Test

The results of the main study on the determination of the auto-ignition temperature of the test item are given in the table below. 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 220°C. This temperature was a multiple of 5°C and therefore given as the auto-ignition temperature of the test item.

Conclusions:
The test item is auto-ignitable with an auto-ignition temperature of 220°C. The atmospheric pressure was between 1020 and 1025 hPa.
Executive summary:

The auto-ignition temperature of the test item was determined in a GLP-compliant study performed in accordance with EC A.15 Method and DIN 51794 Standard. The test item is auto-ignitable with an auto-ignition temperature of 220°C at atmospheric pressure (1020-1025 hPa).

Conclusions:
The auto-flammability temperture of DIOFB was reported as 260 °C according to EU Method A.15. The ambient pressure during the test was 1000.4 hPa to 1018.0 hPa.
Executive summary:

The auto-flammability of DIOFB was determined according to EU Method A.15; however the study was not GLP. Therefore, the study is considered reliable with restrictions.

Description of key information

The auto-ignition temperature of the test item was determined in a GLP-compliant study performed in accordance with EC A.15 Method and DIN 51794 Standard. The test item is auto-ignitable with an auto-ignition temperature of 220°C at atmospheric pressure (1020-1025 hPa). This experimental value is further supported by a non-GLP study reporting an auto-ignition temperature 260°C at atmospheric pressure (1010-1018 hPa).

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
220 °C

Additional information

The auto-ignition temperature of the test item was determined in a GLP-compliant study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint. A non-GLP study is also reported for the endpoint and selected as supporting study (Klimisch 2).
