Measured value: > 110 °C

Determination of the corrected flash-point:

 

TC = T0+ 0.25 x (101.3 – p)

TC = corrected flash point to the standard atmospheric pressure (101.3 kPa)

T0= measured flash point at actual atmospheric pressure

p = actual atmospheric pressure [kPa]

Conclusions:
A flash point value of > 110 °C at 967 hPa was determined in a reliable study conducted according to an appropriate test protocol. It was not compliant with GLP.

Description of key information

191 °C at 974 hPa (EU Method A.9, Pensky Martens closed cup)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
191 °C

Additional information

The key study is supported by a flash point value of >110 °C determined by equilibrium method closed cup method according to EU Method A.9.
