Results


In the thermograms of the two DSC runs a very small endothermic effect was observed in the temperature range of - 50 °C to - 40 °C, which cannot be assigned to the melting of the test item, due to its low energy of < 10 J/g.

Final Results


The test item has no melting point down to -100 °C at atmospheric pressure (1005 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).

Conclusions:
The test item has no melting point down to -100 °C.
Executive summary:

An experimental study was conducted to determine the melting point of the test item according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995) using differential scanning calorimetry. The test item has no melting point down to -100 °C at atmospheric pressure (1005 hPa).

Description of key information

The test item has no melting point down to -100 °C.
