Any other information on results incl. tables
An aliquot (around 25 mL) of test material was placed into a test tube containing a thermometer. A wire loop with which the sample could be agitated was placed inside the tube to ensure sample homogeneity during cooling. The test tube was surrounded by a glass jacket and then placed into a large beaker containing an ice/water mixture, The temperature and observations of the test material were recorded approximately every 30 seconds.
The ice/water was maintained until the test material solidified.
The determination was performed in duplicate.
Graphs of temperature (K) versus time (seconds) were constructed to obtain freezing temperature curves.
Applicant's summary and conclusion
- Conclusions:
- The freezing temperature of Agarbois has been determined to be 283.5 +/- 0.5K (10.35 °C +/- 0.5)
- Executive summary:
The freezing temperature of Agrabois has been determined to be 283.5 +/- 0.5K (10.35 °C +/- 0.5) using a metod based on BS4633: Method for the determination of Crytallizing Point, method A1 of Commission Directive 92/69/EEC
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
