Observations: There was no change in the test item during cooling.

Result:            Freezing temperature: <-20 °C (<253 K).

Applicant's summary and conclusion

Conclusions:
The freezing temperature of the test item has been determined to be less than -20 °C (<253 K).
Executive summary:

The determination was carried out using a procedure designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Conclusion

The freezing temperature of the test item has been determined to be less than -20 °C (<253 K).
