First test results

The heat flow record showed an endothermic effect between 116 °C and 154 °C, with peak at 147 °C and onset at 143 °C. The melting point is 143 °C.

 

Second test results

The heat flow record showed an endothermic effect between 114 °C and 153 °C, with peak at 147 °C and onset at 145 °C. The melting point is 145 °C.

 

Conclusion

The melting temperature of the test item is 144 °C (the mean of two measurements).
