- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: FAT 20037/E TE and Lot: 1501016 - Key result
- Melting / freezing pt.:
- > 350 °C
- Atm. press.:
- 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- ca. 300 °C
- Conclusions:
- The test substance started decomposing at about 300 °C, hence no melting point could be determined.
- Executive summary:
A study according to OECD Guideline 102 was carried out to determine the melting point of the test substance. Differential scanning calorimetry method was used for this purpose. Based on the findings of this study, no melting point for the test substance could be determined till 350 °C, since the substance begin decomposing at about 300 °C.
