Main study
Summarised results of the main study are as follows:
| Test | Volume (µL) | Auto-ignition temperature (°C) | Ignition delay (s) | Colour of the flame | Minimum auto-ignition temperature (°C) |
| 1 | 35 | 436 | 6 | orange/blue | 414 |
| 70 | 414 | 7 | orange/blue | ||
| 150 | 417 | 6 | orange/blue | ||
| 2 | 50 |
427 | 6 | orange/blue | 426 |
| 100 | 426 | 6 | orange/blue | ||
| 200 | 431 | 6 | orange/blue | ||
| 3 | 40 | 442 | 5 | orange/blue | 421 |
| 80 | 421 | 5 | orange/blue | ||
| 140 | 428 | 5 | orange/blue |
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. Hence, according to the guidelines, no further testing was required.
The lowest temperature at which ignition of the test item occurred was 414°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 JNJ-126971-AAA (T000509).
Based on the results of the test performed, the auto-ignition temperature of the test item is 410°C at 1027.4 - 1030.6 hPa. Hence, the test item is considered ‘auto-ignitable’.
