| Analysis/Test | Method | Sample DNA3730/1 (Acid Source) |
| Relative self ignition temperature | EEC A16 | The test started at 150 deg C, the temperature was then ramped 2.0 deg C per minute. DNA3730/1A: The sample did not ignite below 400 deg C. There sample appeared blackened and charred. The test started at 150 deg C, the temperature was then ramped 0.5 deg C per minute. DNA3730/1B: The sample did not ignite below 400 deg C. There sample appeared blackened and charred. The material did not self-ignition below 400 deg C. |
Description of key information
The substance does not self ignite below 200 deg C and is not considered highly flammable.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 200 °C
