Description of key information
Under the conditions of this study, the pour point of the test material was determined to be -18 ± 3 °C (255 ± 3 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -18 °C
Additional information
The key study was conducted in line with GLP and the standardised guidelines OECD 102 and EU Method A.1. It was assigned a reliability score of 1 in accordance with the criteria detailed by Klimisch (1997).
The melting point was determined using the pour point method.
The sample of the test material was heated to 46 °C in a water bath set at 48 °C before being allowed to cool in air to 35 °C. It was then transferred to a bath maintained at -1 to 2 °C, and cooled to 10 °C. At 10 °C, the sample was transferred to a bath maintained at -18 to -15 °C and cooled to -7 °C. Finally, the sample was transferred to a bath maintained at -35 to -32 °C. Starting at -6 °C and at intervals of 3 °C, the sample was tilted to a horizontal position for a period of 5 seconds, during which it was observed for signs of flow.
Under the conditions of this study, the pour point of the test material was determined to be -18 ± 3 °C (255 ± 3 K).
