Type of method:
pour point
Key result
Melting / freezing pt.:
-47 °C
Atm. press.:
1 013 hPa
Remarks on result:
other: arithmetic mean of 2 replicate determinations

Two measurements were performed, with the following results:

-46 °C;

-47 °C;

giving a mean value of -47 °C for the pour point.

Conclusions:
Pour point (DIN ISO 3016 / ASTM D 97): -47° C at 1013 hPa
Executive summary:

The melting point (pour point, determined similar / equivalent to DIN ISO 3016 / ASTM D 97) was determined to be -47 °C (mean of two replicate measurements: -46°C; -47 °C).

The laboratory complied with a quality management system according to DIN EN ISO 9001 : 2008 and DIN EN ISO 14001 : 2005.
