Conclusion

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

Applicant's summary and conclusion

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

The determination was carried out by the pour point method, 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.

Discussion

As the test item was a complex mixture, it was considered that the pour point method was the most appropriate test procedure.

Conclusion

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