Applicant's summary and conclusion

Conclusions:
Based on this observation and the high standard deviation of the replicate measurements the 269 °C is considered to be a decomposition temperature.
Executive summary:

The melting point of a test item is defined as the temperature at which phase transition from a solid to liquid state takes place at normal atmospheric pressure. For the determination of the melting point, the capillary method was used. A small amount of the test item was heated in the electronic controlled sample block and the temperature around the sample was displayed. The melting point was determined based on thermo-optical changes, while raising the temperature. The photosensors continuously measured the intensity of the light transmitted through the samples.

Based on this observation and the high standard deviation of the replicate measurements the 269 °C is considered to be a decomposition temperature.
