- Executive summary:
A study was conducted to determine the melting point of the test substance according to OECD Guideline 102 and EU Method A.1. The test substance was examined by the determination of the pour point according DIN ISO 3016 with constant proceeding cooling was used. No abrupt change of the physical state at a specific temperature was observed, but a continuously increasing viscosity of the sample. The lowest temperature at which movement could be observed was – 38 °C. Under the study conditions, the test substance showed no melting point but a glass transition at -38 °C (Mund, 2017).
