Applicant's summary and conclusion

Conclusions:
The melting/freezing temperature of the test material has been determined to be less than 253 ± 0.5 K.
Executive summary:

The determination was carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86, Method A1 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).

The melting/freezing temperature of the test material has been determined to be less than 253 ± 0.5 K.
