Key result

Decomposition:

yes

Decomp. temp.:

ca. 302 °C

Remarks on result:

other: The test item has been determined to decompose from approximately 302°C (575K) at 100.2kPa

See Thermograms attached

Onset ot decomposition from approximately 302°C (575K). At 400°C the sample had lost approximatley 14% of the original sample weight for determination 2.

Due to the thermogram drifting, it was not possible to determine the exact onset of decomposition, therefore the lowest estimation was used as limit value. Although the residue had darkened in color compared to the initial test item appearance, the sample after being heated to 400°C visually did not show significant decomposition and only approximately 14% of the test item was lost in weight.

Conclusions:

The boiling point of the test material was assessed in accordance with OECD Guideline 103. The test item has been determined to decompose from approximatley 302°C (575K) at 100.2kPa.

Executive summary:

Test Guidance

The determination was carried out by differential scanning calorimetry, using a procedure determined to be compatible with EC Method A2 and OECD Guideline 103
