- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Atm. press.:
- >= 995 - <= 1 005 hPa
- Decomposition:
- yes
- Decomp. temp.:
- 250 °C
- Remarks on result:
- other: The test material has no boiling point up to the decomposition temperature.
- Conclusions:
- Under the conditions of this study, the test material has no boiling point up to the decomposition temperature of 250 °C at atmospheric pressure (995 – 1005 hPa).
- Executive summary:
The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103, EU Method A.2 and EPA OCSPP 830.7220, under GLP conditions using differential scanning calorimetry.
During the heating phase, no thermal effects were observed in the temperature range from -25 to 250 °C. It can be assumed that the test material has no boiling point in this temperature range, i.e. the test material has no boiling point up to a temperature of 250 °C. At approx. 250 °C the test material started to decompose. At approx. 350 °C the exothermic effect ended and an endothermic effect started. The reason for this effect is that some of the decomposition products of the test material start to boil. The endothermic effect ended at approx. 470 °C. No further thermal effects were observed up to the test end temperature of 500 °C.
Under the conditions of this study, the test material has no boiling point up to the decomposition temperature of 250 °C at atmospheric pressure (995 – 1005 hPa).

Additional information
The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103, EU Method A.2 and EPA OCSPP 830.7220, under GLP conditions using differential scanning calorimetry. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
