- Executive summary:
The melting point of the test material with investigated in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions.
The melting behaviour of the test material was estimated in a preliminary test with three replicate samples. Samples of the test material in a glass tube were heated from 30 °C with a rate of 10 °C/min until 400 °C. During the preliminary test melting point was observed around 286.4 °C.
For the main test the capillaries were inserted to the heating chamber at 280 °C, the test material melted immediately. This was the same situation until 150 °C. Therefore a measurement from 150 °C up to 286 °C with 10 °C/min rate was run and considered as second preliminary test.
A heating in the range of 150 to 290 °C was carried out, for this test the test material was powdered if it may be able to exclude the different behaviour of the test material. Even these powdered samples had different behaviour after the insertion the 3 parallel capillaries. It can be stated that a part of the test material disappeared from one capillary (from around 165 °C). The test material in the other two capillaries browned (approximately at 252 °C) and blackened (at around 253 °C).
Under the conditions of the study no exact melting point of the test material could be determined.
