Additional information

Sufficient information is available to conclude that melting point well below likely coldest environmental conditions experienced. The key value selected is the most widely quoted value and one that is reported in source regarded as being reliable. Whilst a measured value is available, this is significantly lower than the handbook values so the latter is used as a conservative choice.
