- Executive summary:
GUIDELINE
Melting point was determined using a method designed to be compatible with Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995, and Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.
METHOD
Melting temperature was determined by differential calorimetry. Two main runs were performed, and the mean final temperature was reported.
CONCLUSION
The melting temperature of the test item has been determined to be over the range 26 to 42 °C (299 to 316 K).
