Any other information on results incl. tables

The tempreature accuracy of the DSC was assessed using indium refernce standard (purity 99.999%). The melting temprature was detrmined to be 156.71°C and withinn the defined toleranz (156.6 +-0.5°C). The DSC was therefore considered as acceptable for use.

Aliquots of test item were placed in pre-pierced aluminium crucibles:
