Applicant's summary and conclusion

Conclusions:
Melting point: 180 Deg C (at Atmospheric pressure: 975hpa)
Executive summary:

The melting point of a substance is the (thermal) point at which a solid substance gains enough thermal energy to become a liquid. Thus is this case the melting point of the substance is found to be 180 °C at using the EPA approved capillary tube method.
