- Executive summary:
A study was conducted according to OECD TG 102, EU method A.1 and EPA OPPTS 830.7200 to determine the pour point of the test item. The pour point was determined from the lowest temperature at which movement of the test item was observed in a closed test jar. The determination was performed in duplicate. The pour point of the test item was determined to be 39 °C at 1013 hPa.
Reference
The test jar was cooled from 44.6 and 44.9 °C and examined at intervals of 3 °C for flow characteristics.
