Remarks on result:
other: Pour point, mean of two replicate determinations

Two measurements were performed, with the following results:

-91 °C;

-89 °C;

giving a mean value of -90 °C for the pour point.

Conclusions:
Freezing point (pour point; DIN ISO 3016 / ASTM D 97): -90 °C
Executive summary:

The freezing point (pour point, determined similar / equivalent to DIN ISO 3016 / ASTM D 97) was determined to be -90 °C (mean of two replicate measurements: -91 °C; -89 °C).
