- Executive summary:
A study was conducted according to OECD test guideline 102 and the Annex to Directive 92/69/EEC, A.1. The melting point was determined with the capillary method. In a preliminary test the approximate melting point was determined and confirmed in the main test. the melting point of the test item was determined to be 72.9 °C.
Reference
Preliminary test
The heat build-up rate to determine the approximate melting range was 10 °C/min. The mean value calculated from the manually generated melting-point values was taken to define the set and max points. The preliminary melting point was calculated to be 77.2 °C.
Measured melting points of the test item (second main test):
