Applicant's summary and conclusion
- Conclusions:
- Using the capillary method with a metal bath, according to the OECD 102 and EU A.1 guidelines, the melting temperature range of the test substance was determined to be between 34.8 and 42 °C with an accuracy of +/- 0.5 °C.
- Executive summary:
The melting point of the test substance has been determined according to EC A.1 method and OECD test guideline 102. Using the capillary method with a metal bath, the melting temperature of the test substance was determined to range between 34.8 °C and 42 °C at ca.1013 hPa.
