GUIDELINE
The determination was carried out by differential scanning calorimetry using a procedure designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
RESULTS
The test item was determined to decompose from approximately 117 °C (390 K) at 102 to 103 kPa after volatilisation of moisture.
