Ignition of the test substance within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 10°C. According to the guidelines, no further testing was required.
The lowest temperature at which ignition of the test substance occurred was 255°C, which is also the auto-ignition temperature if rounded down to the nearest 5°C.Description of key information
By read-across from C16-DMA and C18-DMA (category approach, nearest neighbours), an auto-ignition temperature for C16-18-DMA of 250 °C at atmospheric pressure was derived.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 250 °C
Additional information
The auto-ignition temperature for C16-18-DMA was derived by read-across from C16-DMA and C18-DMA (category approach, nearest neighbours) from the following results obtained for the source substances:
An auto-ignition temperature of the test item C18-DMA of 255 °C (at 1008 hPa) was determined according to EU method A.15 (Siemens, 2011).
An auto-ignition temperature of the test item C16-DMA of 255 °C (at 993 hPa) was determined according to EU method A.15, DIN method 51794 and IEC standard 79-4 (NOTOX, 2010).
An auto-ignition temperature of the test item C16-DMA of 250 °C (at 1007 hPa) was determined according to EU method A.15 (Siemens, 2011).
The lowest temperature obtained from the three available studies was chosen as the key value for chemical safety assessment.
The study results of the source substances were considered applicable to the target substance. Justification and applicability of the read-across approach (category approach) is outlined in the read-across report in the linked category of dimethylalkylamines.
