Any other information on results incl. tables

No information is available regarding atmospheric pressure. Neither endothermic nor exothermic effects were seen in the temperature range of -60 °C to 30 °C (Figures 1, 2). Therefore, the freezing temperature of TFEE-5 is below -60 °C.

Applicant's summary and conclusion

Conclusions:
The freezing temperature of TFEE-5 is below -60 °C.
Executive summary:

The freezing temperature of TFEE-5 was measured using differential scanning calorimetry according to OECD TG103 and EC No. 440/2008.A.1. Neither endothermic nor exothermic effects were observed from -60°C to 30 °C. The freezing temperature of TFEE-5 is below -60 °C.

This study was conducted according to internationally accepted test guidelines but was not conducted according to GLP or an alternate QA standard such as ISO 17025. The study is classified as reliable with restrictions.
