- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -20 °C
- Decomposition:
- no
- Conclusions:
- The freezing/melting point is stated as: < - 20 °C (< 253.15 K).
- Executive summary:
In a pre-test, the test substance was still liquid at - 20.2 °C and frozen at - 80 °C.
According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulationthe determination of the melting- / freezing point does not need to be conducted below a lower limit of - 20 °C.
Therefore, no additional test was conducted and the freezing/melting point is stated as:
< - 20 °C (< 253.15 K).
Reference
Pre-test:
After evaluation the following values were recorded:
Values Pre-Test
Room Temperature |
3.7°C |
-20.2°C |
-80°C |
darkbrown-yellow viscous liquid |
Liquid, like paste |
liquid, like ropy paste |
solid |
Final Result
In a pre-test, the test substancewas still liquid at - 20.2 °C and frozen at - 80 °C.
According toREGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments)by Commission Regulationthe determination of the melting- / freezing point does not need to be conducted below a lower limit of - 20 °C.
Therefore, no additional test was conducted and the freezing/melting point is stated as: < - 20 °C (< 253.15 K).
The appearance of the test substance was stated as darkbrown-yellow viscous liquid.
Description of key information
The freezing/melting point is stated as:
< - 20 °C (< 253.15 K).
