Results and discussion

Auto-ignition temperature (liquids / gases)

Key result

Auto-ignition temperature:

410 °C

Atm. press.:

>= 1 018 - <= 1 023 hPa

Remarks on result:

other: The test item is auto-ignitable

Any other information on results incl. tables

 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 < 20°C.

 The lowest temperature at which ignition of the test item occurred was 412°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 410°C

Applicant's summary and conclusion

Conclusions:

A commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of Cyclopentylchloride.

The test item is auto-ignitable with an auto-ignition temperature of 410°C at 1018 - 1023 hPa.
