- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- equilibrium method closed cup
- Flash point apparatus:
- other: Normalab NPV 310
- Key result
- Flash point:
- > 195.5 °C
- Atm. press.:
- 1 013 hPa
- Remarks on result:
- other: At 195°C vigorous formation of aerosol was observed. It was assumed that the test item started to boil. Therefore, the test was stopped at 195.5°C, no ignition was observed up to 195.5°C.
- Interpretation of results:
- GHS criteria not met
- Executive summary:
In the Klimisch 1 study from Nau (2017) the flashpoint of DCA was determined according to EU method A.9. using the equilibrium closed cup method. At 195°C vigorous formation of aerosol was observed. It was assumed that the test item started to boil. Therefore, the test was stopped at 195.5°C, no ignition was observed up to 195.5°C.
The result is considered relevant and reliable for the risk assessment.

Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 195.5 °C
Additional information
In the Klimisch 1 study from Nau (2017) the flash point of DCA was determined according to EU method A.9. using the equilibrium closed cup method. At 195°C vigorous formation of aerosol was observed. It was assumed that the test item started to boil. Therefore, the test was stopped at 195.5°C, no ignition was observed up to 195.5°C.
The result is considered relevant and reliable for the risk assessment.
Further supporting information provided in the handbook from Brandes and Möller (2003) indicate that the flash point of DCA is >110 °C.
