- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Melting / freezing pt.:
- > 350 °C
- Conclusions:
- Chromium (III) hydroxide sulphate exhibits no melting effects up to 350 °C.
- Executive summary:
The melting point of the sample was assessed in a GLP-study according to EU Method A.1 via differential scanning calorimetry. The sample exhibits no melting effects up to 350 °C. Multiple endothernic effects were observed at about 60 °C. This was caused by the release of water during crystallization.

Additional information
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.
