* not used for test evaluation

Starting at approx. 290 °C decomposition occurred. Therefore, the last two measurements were not used for the test evaluation and no values could be taken during cooling-down process. The vapour pressure of the test item at 20 °C was calculated by mathematical extrapolation using the Antoine equation. It was calculated to < 0.1 hPa (at 20 °C).

Conclusions:
The vapour pressure of the test item was determined according to OECD Guideline 104 [adopted on
23 March 2006] and EU test method A.4 [Council Regulation (EC) No 440/2008] with the dynamic method.
Vapour pressure (at 20 °C): < 0.1 hPa

Description of key information

The vapour pressure has been measured to be below < 0.1 hPa at 20 °C according to OECD TG104 and EU test method A.4 .

Key value for chemical safety assessment

Vapour pressure:
0.1 hPa
at the temperature of:
20 °C

Additional information

The vapour pressure of the test item has been determined in a GLP conform study according to OECD Guideline 104 and EU test method A.4 with the dynamic method. The vapour pressure has been measured to be below < 0.1 hPa at 20 °C.
