- Executive summary:
The melting temperature of the test material was assessed according to OECD Test Guideline 102 and EU Method A.1 and in compliance with GLP using a Differential Scanning Calorimeter.
The DSC curve of the preliminary test (heating rate of 20 °C/min from 25 °C to 400 °C) showed there were no endothermic heat effects observed from which melting could be deduced. An exothermic reaction could be observed starting at about 250 °C caused by the decomposition of the test material. After the experiment, the sample was still a powder but changed its colour to black and lost about 27 % of its mass.
To confirm the results of the preliminary test, a main test run was performed. A test material amount of 3.16 g was heated up from 25 °C to 400 °C at a rate of 10 °C/min. No endothermic reaction could be observed from which melting could be deduced. An exothermic reaction could be observed starting at about 250 °C caused by the decomposition of the test material. After the experiment the sample had lost about 30 % of its mass and the sample was a black powder.
Under the conditions of the study the test material did not melt.

Preliminary Test
The DSC curve of the preliminary test (heating rate of 20 °C/min from 25 °C to 400 °C) showed there were no endothermic heat effects observed from which melting could be deduced. An exothermic reaction could be observed starting at about 250 °C caused by the decomposition of the test material. After the experiment, the sample was still a powder but changed its colour to black and lost about 27 % of its mass.
Main Test
To confirm the results of the preliminary test, a main test run was performed. A test material amount of 3.16 g was heated up from 25 °C to 400 °C at a rate of 10 °C/min. No endothermic reaction could be observed from which melting could be deduced. An exothermic reaction could be observed starting at about 250 °C caused by the decomposition of the test material. After the experiment the sample had lost about 30 % of its mass and the sample was a black powder.
Under the conditions of the study the test material did not melt.

Additional information
The melting temperature of the test material was assessed according to OECD Test Guideline 102 and EU Method A.1 and in compliance with GLP using a Differential Scanning Calorimeter. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
