- GLP compliance:
- yes (incl. QA statement)
- Auto-ignition temperature:
- 330 °C
- Atm. press.:
- 1 018 hPa
- Conclusions:
- An auto-ignition temperature of 330 °C was found for dimethyl (dimethoxyphosphinyl)succinate at 1018 hPa.
- Executive summary:
The test was performed as stipulated in EC Test Procedure A.15 'Auto-ignition temperature (liquids and gases)' (DIN 51794 - Determining the ignition temperature of petroleum products).
In every ignition test, a small portion of the flammable substance under test was introduced into an open conical flask (Erlenmeyer flask). The flask was heated in an electric furnace and it was observed whether ignition takes place at the prevailing temperature. Finally, any vaporizable components left in the flask were blown out with air. An ignition was observed at a temperature of 340 °C at a sample size of five drops (lowest value of first test run). Proceeding from this temperature, the lowest value in the main test run was found at 335 °C. A repeat test was performed using fresh ignition vessels. The lowest value in the repeat test was also found at 335 °C. The barometric pressure was 1018 hPa at the time of the test runs. Thus auto-ignition temperature of 330 °C was determined for dimethyl (dimethoxyphosphinyl)succinate at 1018 hPa.
Reference
An ignition was observed at a temperature of 340 °C at a sample size of five drops (lowest value of first test run). Proceeding from this temperature, the lowest value in the main test run was found at 335 °C. A repeat test was performed using fresh ignition vessels. The lowest value in the repeat test was also found at 335 °C. Bearing in mind the significance of the ignition temperature for risk assessment, the result is not reported as the mean, but as the lowest value, where ignition occurs, rounded down to the next multiple of 5 °C.
Description of key information
An auto-ignition temperature of 330 °C was found for dimethyl (dimethoxyphosphinyl)succinate at 1018 hPa.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 330 °C
Additional information
As 1018 hPa and 1013 hPa are very similar pressures the auto-ignition temperature will not vary between these values.
