Preliminary Test

The estimated auto-ignition temperature was 505°C.

Main Study

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 463°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 460°C.

Conclusions:

The test item is auto-ignitable with an auto-ignition temperature of 460°C. The atmospheric pressure was between 1020 and 1021 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 460°C at atmospheric pressure (1020 -1021 hPa).

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 460°C at atmospheric pressure (1020 -1021 hPa).This experimental value is further supported by non-GLP studies, performed according to recognized guideline (ASTM E 659 ) and reporting an auto-ignition temperature of 453°C and 485°C at atmospheric pressure.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

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. The non-GLP studies are also reported for the endpoint and selected as supporting study (Klimisch 2).
