- Key result
- Auto-ignition temperature:
- 175 °C
- Atm. press.:
- > 1 006.9 - < 1 013.4 hPa
- Conclusions:
- The auto-ignition temperature of the test item is 175°C at1006.9 to 1013.4 hPa.
- Executive summary:
The auto-ignition temperature was determined according to recognized guidelines (Eu method A.15, DIN 51794 and IEC 60079.4) and under GLP.
No deviation from the guidelines was observed during the test.
The behaviour of the test item was studied in a preliminary test. Then a main study, consiting of 3 tests was performed.
The auto-ignition temperature of the test item is 175°C at 1006.9 hPa to 1013.4hPa.
Reference
Preliminary test:
The auto-ignition temperature was estimated to be 225°C.
Main study:
| Test | Volume of sample (µl) | Auto-ignition temperature (°C) | Minimum auto-ignition temperature (°C) |
1 |
70 | 226 | 179 |
| 150 | 201 | ||
| 300 | 190 | ||
| 600 | 179 | ||
| 800 | 182 | ||
| 2 | 250 | 187 | 178 |
| 500 | 178 | ||
| 900 | 185 | ||
| 3 | 350 | 186 | 181 |
| 700 | 181 | ||
| 1000 | 192 |
The all the test, the ignition delay was inferior to 2 minutes and the color of the flame observed was blue.
The deviation between the values obtained in the three tests was lower than 10°C. According to the guidelines, no further testing was required.
The lowest temperature at which inginition occured was 178°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of 175°C.
Description of key information
The auto-ignition temperature was determined according to recognized guidelines (EU method A.15, DIN 51794 and IEC 60079.4) and under GLP.
No deviation from the guidelines was observed during the test.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 175 °C
