Any other information on results incl. tables
Preliminary Test:
An approximate value of the ignition temperature of the test item was first determined by a preliminary test. The tables given below gives the result of the preliminary test. An ignition is denoted as “+” and no ignition is denoted as “-”. 5 drops were put into the Erlenmeyer flask at each temperature.
In the preliminary test, the lowest temperature at which an ignition occurred was 291 °C.
| Temperature (°C) | Ignition (+/-) |
| 208 | - |
| 249 | - |
| 300 | + |
| 291 | + |
| 282 | - |
| Atmospheric pressure: 1005.2 hPa | |
Main Test
The lowest temperatures at which an ignition occurred in the main test are given in this table (below).
| Main test series | Lowest temperatures of an ignition (°C) | Highest temperatures without an ignition (°c) | Atmospheric Pressure (hPa) |
| 1 | 258 | 256 | 1001.2-1003.8 |
| 2 | 256 | 254 | 1007.2-1007.5 |
| 3 | 256 | 254 | 1005.8-1007.3 |
Based on results of the main test series, the lowest auto-ignition temperature was 256 °C.
Regulation (EC) No 440/2008 and DIN 51794: The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 255 °C.
For information:
DIN EN 14522: The auto-ignition temperature reduced by 1.5 % and rounded to the nearest integer temperature was determined as 252 °C.
Applicant's summary and conclusion
- Conclusions:
- The test item Triethylene glycol dimethanesulfonate (CAS no. 80322-82-3) has an autoignition temperature of 255 °C according to the Regulation (EC) No 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Testing of mineral oil hydrocarbons – Determination of ignition temperature.
It is noted here that according to ECHA guidance – Guidance on information requirements and chemical safety assessment; chapter R.7A: Endpoint specific guidance, July 2017 – the autoignition temperature for liquids is not used directly for classification and labeling according to Regulation (EC) 1272/2008. However, it can be used in the chemical safety assessment in considering risks associated with processing the substance.
According to DIN EN 60079-0 the test item has to be assigned to temperature class T3. - Executive summary:
The test item Triethylene glycol dimethanesulfonate (CAS no. 80322-82-3) has an autoignition temperature of 255 °C according to the Regulation (EC) No 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Testing of mineral oil hydrocarbons – Determination of ignition temperature.
