Because the difference between the two main measurements was < = 5.1 (mean value x 0.029), a second main test was not necessary.

The flash point of the test item was determined according to EU test method A.9 (Council Regulation (EC) No. 440/2008, Official Journal L 142/1 2008) with the Pensky-Martens method (closed cup).

Flash point: 175 °C (1013 hPa)

Conclusions:
A flash point value of 175 °C at 1013 hPa was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP.

Description of key information

175 °C at 1013 hPa (EU Method A.9, equilibrium method, closed cup)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
175 °C

Additional information

The key study is supported by a measured flash point of 84°C at 1013 hPa determined using the equilibrium method (closed cup) according to EU Method A.9. The lower value of the second study may be due to the presence of volatile solvent. Measured values of 119.5°C, 165°C and 122°C have also been obtained from secondary sources (company data and MSDS).
