- Key result
- Melting / freezing pt.:
- < -29 °C
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The freezing point of the test item is < -29 °C.
- Executive summary:
An experimental study was conducted according to Regulation (EC) No 440/2008 Method A.1. and OECD Test Guidelines 102 to determine the freezing point of the test item. In a pre-test the test item was stored in the freezer with a temperature of -29 °C. The test item remained liquid after storage for 48 h. Therefore, the main test to determine the exact freezing temperature was not conducted. The freezing point of the test item is < -29 °C.
