- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 22 Februar - 19 August 2022
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
- Version / remarks:
- 2021
- Qualifier:
- according to guideline

- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source (i.e. manufacturer or supplier) and lot/batch number of test material: Manufacturer, UA21412002
- Purity, including information on contaminants, isomers, etc.: Content: 75% 3-(N,N-Dimethyl)propyl-urea and 25% Polyethylenglycol
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Store container tightly closed at a well-ventilated place. Store in the original container. Do not store with acids. - Key result
- Flash point:
- > 133 °C
- Atm. press.:
- 1 010 hPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item PU-2021-971 does not have a flash point up to 133 °C according to Regulation (EC) No 440/2008 Method A.9. Flash Point and DIN EN ISO 2719 (2021).
According to the results of the test on the flash point, the test item is classified as follows:
UN Transport Regulation: As the test item has no flash point up to 133 °C (> 60 °C), it has not to be classified as flammable liquid of UN Class 3.
Attention: Under the transport regulation special rules apply to viscous compounds.
GHS (CLP Regulation (EC) No 1272/2008 Annex I: 2.6): As the test item has no flash point up to 133 °C (> 60 °C), it has not to be classified as flammable liquid.
Reference
Preliminary Test
The result of the preliminary test with the search program is summarized in the following table. The result “ignition” is indicated by “+” and “no ignition” by “-”.
Table 1- Results of the reliminary test
Amount of test item / g | Temperature / | Ignition | Air pressure / hPa |
67.7 | 35 - 133 | - | 1008.1 |
The flame is extinguished by evaporating test item at 133 °C in the preliminary test.
Main Test
Table 2: Results of the main test
Amount of test item / g | Temperature / | Ignition | Air pressure / | Corrected flash point / °C |
64.8 | 111 - 133 | - | 1008 | - |
65.3 | 111 - 133 | - | 1012 | - |
Again, the flame is extinguished by evaporating test item at 133 °C. Therefore, the test item has no flash point up to 133 °C.
Description of key information
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 133 °C
