Applicant's summary and conclusion

Conclusions:
Freezing point: -7.9ºC
The study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability).
Executive summary:

The test substance was placed in a test tube and then stirred continuously while placed in a -30°C dry ice/ethanol bath. The temperature was recorded continuously throughout the cooling. Plotted the temperature vs. time. The freezing point was determined graphically.

Freezing point is -7.9°C (average of two replicates (-8.2°C and -7.5°C)).
