Mean value*

85.0 °C

*The mean value is calculated from test 1 and 2 and rounded to ± 0.5 °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 of 85.0°C was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with ISO 9001:2008. The result is considered to be reliable.
