Overall pour point result: -15 ± 3 °C (258 ± 3 K)

Conclusions:
The pour point of the test item has been determined to be -15 ± 3 °C (258 ± 3 K).
Executive summary:

The pour point of the test item was determined to be -15 ± 3 °C (258 ± 3 K), using the pour point method, 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. As the test item is a complex mixture, it was considered that the pour point method was the most appropriate test procedure.

Description of key information
