 Preliminary test

The estimated auto-ignition temperature was 530°C.

 

 Main study

The results of the main study on the determination of the auto-ignition temperature of the test substance are given inTable11.

 

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 < 20°C. According to the guidelines, no further testing was required.

 

The lowest temperature at which ignition of the test substance occurred was 523°C. This temperature was rounded off to the nearest multiple of 5°C giving an auto-ignition temperature of the test substance of 520°C.

Applicant's summary and conclusion

Conclusions:

Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of the reaction mass containing mainly 2-chloropropene.

The test substance is auto-ignitable with an auto-ignition temperature at 1011.5 – 1017.0 hPa of 520°C.
