- Executive summary:
Melting/Freezing Temperature. Decomposed from approximately 275 °C (548 K), by differential scanning calorimetry, designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. As the test item decomposed, no value for melting temperature could be determined.
