Conclusions:
The pour point of the test item has been determined to be less than -20 ± 3°C (<253 ± 3 K).
Executive summary:

The pour point of the test item has been determined to be less than -20 ± 3°C  (<253 ± 3 K), using BS 2000: Part 15 (equivalent to ISO 3016), designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Description of key information

The pour point of the test substance was determined to be less than -20 ± 3°C (<253 ± 3 K), using the pour point method BS 2000: Part 15 (equivalent to ISO 3016), designed to be compatible with EC test method A.1, under GLP conditions (Butler and White, 2010).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C

Additional information

The pour point is determined to be below -20 °C; the bounded value of - 20 °C can be used for the CSA.
