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. According to the guidelines, no further testing was required.

The lowest temperature at which ignition of the test substance occurred was 215°C, which is also the auto-ignition temperature if rounded down to the nearest 5°C.

Applicant's summary and conclusion

Conclusions:
The test substance is auto-ignitable with an auto-ignition with an auto-ignition temperature of 215ºC.
Executive summary:

The test was performanced according to EU method A.15, DIN method 51794 and IEC standard 79-4. A commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of the substance. The test substance is auto-ignitable with an auto-ignition temperature 215ºC.
