Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- > 400 °C
Any other information on results incl. tables
After measurement, the the test item was colored dark brown and had lost about 14 % of its mass and still remained a powder. The test item did not melt under the applied test conditions.
Applicant's summary and conclusion
- Conclusions:
- The substance does not melt under the conditions of the test.
- Executive summary:
The determination of the melting point / melting range of the test item was performed according to the EEC Directive 92/69, A.1 "Melting/Freezing temperature", December 1992 and to the OECD Guideline No. 102: " Melting point I melting range", adopted July 27, 1995.
An endothermic heat effect was observed between about 80 °C and 180 °C. An exothermic heat effect starts at about 320 °C. After the experiment, the sample still remained a powder and its colour was changed to dark brown.
In the main study (heating rate of 10 K/min from 25 °C to 400 °C) the result of the preliminary test was confirmed. The test item lost about 14 % of its mass and still remained a powder. The colour had changed from red to dark brown. Thus it is obvious that the test item did not melt under the applied conditions.
In conclusion, the test substance does not melt under the conditions of the test.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
