- Key result
- Auto-ignition temperature:
- 250 °C
- Atm. press.:
- 994 hPa
- Remarks on result:
- other: Time lag: 4 minutes
- Conclusions:
- The auto ignition temperature of nopyl acetate was determined to be 250 °C at 994 hPa.
- Executive summary:
The determination of the auto flammability was performed in accordance with EU Method A.15 and the Standard Test Method DIN 51794.
In the preliminary test, ignition was observed at around 260 °C at 994 hPa.
In the main test, the auto ignition temperature of nopyl acetate was determined to be 250 °C at 994 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 994 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 |
| 240°C | No ignition | No ignition | No ignition | No ignition | No ignition |
| 250°C | No ignition | No ignition | No ignition | No ignition | Ignition |
| 260°C | Ignition | - | - | - | - |
During the main test the auto-ignition temperature of nopyl acetate was determined to be 250°C at 994 hPa.
Description of key information
The auto ignition temperature was determined according to the DIN 51794 standard method.
The auto ignition temperature of nopyl acetate is 250 °C at 994 hPa.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 250 °C
Additional information
Key study conducted according to EU Method A.15 and DIN 51794 standard method. The result is scientifically acceptable but not obtained under GLP. Therefore a reliability of 2 (reliable with restrictions) is assigned. The result can be used as key value for chemical safety assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
