- Key result
- Auto-ignition temperature:
- 310 °C
- Atm. press.:
- >= 997.6 - <= 1 011.7 hPa
- Conclusions:
- The auto-ignition temperature of the test item was determined to be 310 °C.
- Executive summary:
A study was conducted according to Regulation (EC) No. 440/2008, Method A.15. The main test is started at the lowest auto-ignition temperature found in the preliminary test and the temperature then decreased in intervals of 2 – 5 K. The amount of test item added to the apparatus is varied until a temperature is found where no ignition is observed independent of the amount of test item added. Three test series were carried out. The lowest auto-ignition temperature rounded down to the nearest multiple of 5 was determined as 310 °C.
Reference
The results of the main test are compiled in table 1.
Table 1: Auto-ignition temperature (summary)
Main test series | Auto-ignition temperature / °C | Time lag / s |
1st main test (5 K) | 317 | 42 |
1st main test (2 K) | 319 | 30 |
2nd main test (2 K) | 317 | 41 |
3rd main test (2 K) | 315 | 30 |
The lowest auto-ignition temperature of the test item was determined to be 315 °C in the main test.
Due to safety reasons and according to the guidelines the lowest measured temperature at which an ignition was observed was rounded to the next lower number divisible by 5, giving a value of 310 °C.
Description of key information
The auto-ignition temperature of the test item was determined to be 310 °C (reference 4.12-1).
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 310 °C
