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 494°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 490°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 JNJ-7928531-AAA (T001481). The test item is auto-ignitable with an auto-ignition temperature of 490°C at 1020.7 – 1022.6 hPa.
