 ENI  211

Result and Discussion

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 212 ± 1.4 °C (mean ± standard deviation).

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

Conclusions:
The flash point is given as the mean value of the duplicate determination. The measured flash point is 212 ± 1.4 °C (mean ± standard deviation).
The difference between the two values which were measured was below 2 K. For this reason, the determination was considered valid.

Description of key information
