The study was performed in order to determine the flash point of test item according to EU A.9 guideline, using an equilibrium method with closed cup.
No flash point was observed between 25.0 °C and 100.0 °C using 2 ml of the substance
The lowest flash point (without correction) was observed at 95.0 °C using 4 ml ofthe substance.
The test item is NOT classified as flammable liquid according to Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS).
Reference
Results
Pre-test
The flash point of the test item was estimated at 100.0°C during the pre-test.
Main determination
Several trials were then performed by varying the amount of substance and the starting temperature. Some trials were performed using the same sample as for the previous trial.
The table below summarizes trial conditions and corresponding results:

It appears that the lowest flash point was observed at 95°C using 4 mL of the substance (trial 7). No flash point was observed using 2 mL until 120°C (start temperature 100°C; trial 10). When a sample of 4 mL is used, flash point is systematically observed. When the substance (4 mL) has just been poured into the apparatus, a flash is observed during the first dipping of the ignitor into the cup. However, if a measurement is performed on a sample which has already flashed (trials 1,2 and 3), the flash is not systematicallyobserved at the same temperature.
Control of the performance of the method:
The reference substance Certified Reference Material (CRM), for which a flash point of 75.5°C has been determined following ISO 34 and ISO 35,was used to check the performance of the method.
A flash point of 76°C was registered for theCertified Reference Material (Batch N° 1162111a)
Conclusion
No flash point was observed between 25.0 °C and 100.0 °C using 2 ml of the substance
The lowest flash point (without correction) was observed at 95.0 °C using 4 ml ofthe substance.
Description of key information
No flash point was observed between 25.0 °C and 100.0 °C using 2 ml of the substance
The lowest flash point (without correction) was observed at 95.0 °C using 4 ml ofthe substance.
Test item is NOT classified as flammable liquid according to Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 95 °C
Additional information
A fully reliable experimental study, conducted according to EU A9 guideline is available.
It is considered as a key study, and the result is retained as key data.
