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 255°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 temperature at 992.4 and 994.3 hPa of 255ºC.
- 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 255ºC.
