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 183 °C (456 K) at 98 kPa.

RESULTS
- Thermograms for determinations 1 and 2 are shown in Figures 3 and 4 (attached).
- Thermographic data are summarised in Table 4 (below).
- After heating to 400 °C, the samples had lost approximately 82 and 77 % of their original weight respectively.
