- Key result
- Auto-ignition temperature:
- 260 °C
- Atm. press.:
- 986 hPa
- Remarks on result:
- other: Time lag: 4 minutes
- Conclusions:
- The auto ignition temperature of nopol was determined to be 260 °C at 986 hPa.
- Executive summary:
The determination of the auto flammability was performed in accordance with regulation (EC) No 440/2008 method A.15 "Auto-Ignition Temperature (Liquids and Gases)" (May 2008) and the Standard Test Method DIN 51794.
In the preliminary test, ignition was observed at around 260 °C at 986 hPa.
In the main test, the auto ignition temperature of nopol was determined to be 260°C at 986 hPa.
Reference
Preliminary study:
Time lag: 4 minutes ; amount 5 drops = 3 mL
| Temperature | Results |
| 240°C | No-ignition |
| 260°C | Ignition |
The preliminary results indicate that the auto-ignition temperature is aroud 260°C at 986 hPa.
Main study:
Time lag: 4 minutes ; amount of test item: 1 to 5 droplets = 0.6 to 3 mL
| Temperature | exp 1 | exp 2 | exp 3 | exp 4 | exp 5 |
| 250°C | No ignition | No ignition | No ignition | No ignition | No ignition |
| 260°C | Ignition | - | - | - | - |
During the main test the auto-ignition temperature of nopol was determined to be 260°C at 986 hPa.
Description of key information
The auto ignition temperature was determined according to the DIN 51794 standard method.
The auto ignition temperature of nopol is 260 °C at 986 hPa.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 260 °C
Additional information
Key study conducted according to EU Method A.15 and DIN 51794 Method. The result is scientifically acceptable but not obtained under GLP. Therefore a reliability of 2 (reliable with restrictions) is assigned.
