- Executive summary:
A study was conducted to determine the melting point/glass transition temperature of the test substance according to a differential scanning calorimetry (DSC) method. Duplicates of the test substance were encapsulated in Al pans with pierced lids. Instruments were calibrated with an indium and zinc standard following internal procedure. Experimental melting points (Tm) corresponded to literature values; 156.6°C/419°C (Tm indium/Tm zinc). Samples were submitted to a temperature program going from -60°C to 500°C with a speed of 10K/min. Under the study conditions, the freezing point of the test substance was -10.7°C (Sohar, 2016).
