Applicant's summary and conclusion

Conclusions:
The density of the test item has been determined to be 1.25 x 103 kg/m3 at 19.0 ± 0.5 °C; relative density: 1.25.
Executive summary:

The general physico-chemical properties of 5007 TDS HYDRATE SEC have been determined. The results are summarized below:

Boiling Point : As the test item was identified as decomposing prior to melting, no determination of the boiling point was feasible by Method A.2 Boiling Temperature of
