The flash point of the test item was 93.5 °C ± 0.5 °C (corrected value).

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item was 93.5°C (corrected to standard atmospheric pressure). According to GHS criteria, the test item is not considered as a flammable or combustible liquid (flash point > 93°C).
Executive summary:

The flash point of the REACH substance was determined in a GLP-compliant study performed in accordance with EC A.9 method and ISO 3679 method (equilibrium closed cup method). The flash point of the test substance was 93.5°C (corrected to standard atmospheric pressure). According to GHS criteria, the test item is not considered as a flammable or combustible liquid (flash point > 93°C).
