Test Guidance
OECD Guideline 102 (Melting point / Melting Range)
Method and Material
A sample of test material was poured into a test jar which was then enclosed in a glass jacket. The sample was heated to 46°C in a water bath set at 48°C before being allowed to cool in air to 35°C. The sample was transferred to a bath maintained at -1°C to 2°C and cooled to 10°C, then transferred to a bath maintained at -18°C to -15°C and then cooled to -7°C. The sample was transferred to dry ice/acetone bath maintained at -35 to -32°C. Starting at -9°C and at intervals of 3°C, the sample was tilted to a horizontal position for a period of 5 seconds, during which the sample was observed for signs of flow.
Result
The pour point of the test material has been determined to be 255 ± 3 °K (-18°C).
