Conclusions:
The Freezing point determination of test chemical was done using crushed ice and salt. (type of bath). No freezing was observed up to -8.57 °C. Hence, the freezing point was inferred to be less than -8.57 °C at 971.2 hPa.
Executive summary:

The Freezing point determination of test chemical was done using crushed ice and salt. (type of bath). No freezing was observed up to -8.57 °C. Hence, the freezing point was inferred to be less than -8.57 °C at 971.2 hPa.

Description of key information
