Any other information on results incl. tables

Preliminary test

The estimated auto-ignition temperature was 455°C.

 

Main study

The results of the main study on the determination of the auto-ignition temperature of the test item are given in 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 < 20°C. According to the guidelines, no further testing was required.

 

The lowest temperature at which ignition of the test item occurred was 459°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 455C.

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 JNJ-54582034-AAA (T003642).

The test item is auto-ignitable with an auto-ignition temperature of 455°C at 1016.4 – 1021.3 hPa.
