Description of key information

2 measurements are available.

The first measurement was performed in October 2003 for the purpose of new substance registration according to Directive 67/548/EEC. No endothermal process (melting) could be observed in the differential scanning calometry and an exothermal event was observed at about 180°C which had been attributed to a decomposition reaction.

The second measurement, representing the actual manufactured material, was performed in January 2020. This result is regarded as more reliable since recently manufactured testmaterial was measured using a state of the art and software controlled device and applying a reduced heating rate (3 K/min instead of 5 or 10 K/min).

Hence, this study is judged as the key study.
