Conclusions:
The vapour pressure of the test substance was < 1.5 x 10-3 Pa at 20°C (293K) and < 5.8 x 10-3 Pa at 25°C (298K).
Executive summary:

The vapour pressure of the test substance was determined according to OECD guideline 104 and EU method A.4. The isothermal TGA effusion method was applied. The vapour pressure of the test substance was < 1.5 x 10-3 Pa at 20°C (293K) and < 5.8 x 10-3 Pa at 25°C (298K).
