Applicant's summary and conclusion

Conclusions:
The testing substance Actinol has its melting point at 49.3 +/- 0.1 °C or 322.5 +/- 0.1 K.
Executive summary:

The determination of the melting point of the test substance Actinol was performed according to the EEC Directive 92/69, A.1, 1992, and the OECD Guideline No. 102, 1995.

The results of six individual tests are shown in table 1. A total of 6 samples were heated at the relevant temperature with a heating rate of 0.5 K/min. All samples were completely melted between 49.2 ° and 49.3 °C. After the measurement, the samples were melted and colourless.

In conclusion, the melting point of Actinol is 49.3 +/- 0.1 °C.
