 Sample  Sample weight (mg)  Onset of effect (deg C)  Range of effect (deg C)  Weight loss (mg)  Atmospheric pressure (hPa)
 1  14.06  70.09  60 - 80 (endothermic)  14.01  1009
 2  14.84  70.65  60 - 80 (endothermic)  14.83  1009
Conclusions:
The test item has a melting point of 70.4 °C at atmospheric pressure (1009 hPa).
Executive summary:

The test item has a melting point of 70.4 °C at atmospheric pressure (1009 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995). This study is considered to be reliable without restrictions (Klimisch 1). The study was not GLP-compliant, however the testing laboratory holds a GLP certificate.
