Because the difference between the two main test measurements was <= 2.3 (mean value x 0.029), a second main test was not necessary.

Interpretation of results:
GHS criteria not met
Conclusions:
A flash point value of 79°C at 1013 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.

Description of key information

Flash point: 79°C at 1013 hPa (ISO 2719)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
79 °C

Additional information

A measured flash point value of 79°C at 1013 hPa was determined for the substance using a closed-cup method in accordance with ISO 2719 Test Method and in compliance with GLP. The result is considered to be reliable and is selected as the key study.

The key study is supported by a measured flash point of 86°C at 1013 hPa which was determined for the substance using a closed-cup method.

In available secondary sources to which reliability could not be assigned, flash point values of >40°C, 45°C, 51.5°C, 57°C and 84°C were reported for the substance.

Variations in the flash point values may be caused by variations in purity of the test substance and in the test method used. In particular, the presence of higher concentrations of methanol, a hydrolysis product of the substance, will result in lower flash points.

A measured flash point of 79°C at 1013 hPa and a measured boiling point of 199°C indicate that the substance should not be classified for flammability in accordance with Regulation (EC) No. 1272/2008.
