The vapour pressure of the test substance 70 % (60 % TLA) was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline 104 (2006).

Conclusions:
Under the study conditions, vapour pressure of the test substance was established to be 1450 Pa at 20 °C, 1950 Pa at 25 °C and 7450 at 50 °C.
Executive summary:

A study was conducted to determine the vapour pressure according to OECD Guideline 104 and EU Method A.4. The vapour pressure of the test substance was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C. Under the study conditions, vapour pressure of the test substance was established to be 1450 Pa at 20 °C, 1950 Pa at 25 °C and 7450 at 50 °C (Möller, 2017).

Description of key information

The vapour pressure was determined according to OECD Guideline 104 and EU Method A.4 (Möller, 2017).

Key value for chemical safety assessment
