Evaluation and Result


The flash point is given as the mean value of the duplicate determination. The measured
flash point is therefore 98.0 ± 0.5 °C (corresponding to 371.2 ± 0.5 K).


The difference between the two values which were measured was below 2 K. For this reason,
the determination was considered valid.

Interpretation of results:
GHS criteria not met
Remarks:
EU-CLP criteria not met
Conclusions:
The flash point of the test item is 98.0 ± 0.5°C (371.2 ± 0.5 K).

The flash point of the test substance is above the classification threshold of 60 °C (CLP criteria) and 93 °C (GHS criteria). Therefore, the test substance is NOT a flammable liquid according to GHS and CLP criteria.
Executive summary:

The flash point of test item was determined under GLP according to the EU method A.9, OPPTS 830.6315 and UN Manual Test Methods 32.4.


The flash point of the test item is 98.0 ± 0.5 °C (371.2 ± 0.5 K)(mean value of two independant determinations).


The flash point of the test substance is above the classification threshold of 60 °C (CLP criteria) and 93 °C (GHS criteria). Therefore, the test substance is NOT a flammable liquid according to GHS and CLP criteria.


 

Description of key information

The flash point of the test item is 98.0 ± 0.5°C (371.2 ± 0.5 K).


The flash point of the test substance is above the classification threshold of 60 °C (CLP criteria) and 93 °C (GHS criteria). Therefore, the test substance is NOT a flammable liquid according to GHS and CLP criteria.


Note that the result obtained on this kind of substance could be largely influence by small amounts of volatile constituents.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
98 °C

Additional information

The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), OPPTS 830.6315 and UN Manual Test Methods 32.4., using a non-equilibrium closed cup method. It is considered as a key study and the result is retained as key data.
