Applicant's summary and conclusion

Conclusions:
Polyperin Y has been determined to decompose from 548 ± 0.5 K prior to melting.
Executive summary:

The determination of the melting point / melting range of the test item was performed according to the EEC Directive 92/69, A.1 "Melting/Freezing temperature", December 1992 ; (which constitutes Annex V of Council Directive 67/548/EEC) under GLP. The determination was carried out using the capillary method/melting temperature devices with liquid bath.

Polyperin Y has been determined to decompose from 548 ± 0.5 K (274.85 °C) prior to melting.
