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

The melting/ freezing point of the test item was determined to be less than -20 °C (<253 K), using a procedure designed to be compatible with Method A.1 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.
