Applicant's summary and conclusion

Conclusions:
Melting point of disodium 4,4'-dinitrostilbene-2,2'-disulphonate is 525 deg C at 960 hPa
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 in this case the melting point of disodium 4,4'-dinitrostilbene-2,2'-disulphonate is 525 deg C at 960 hPa.
