Additional information

Value extrapolated from DEZA measurement is very high due to the fact that the scope of measurement is between 135 - 340°C.

On the other hand, the Huels AG Marl data were measured in scope 25 and 80°C, so in this case are more suitable for extrapolation in standard conditions. However, figures measured by Syracuse Research Corporation are more accurate.
