- #2
- Temp.:

- Vapour pressure:
- 0.13 hPa
- Key result
- Test no.:

- Temp.:
- 50 °C
- Vapour pressure:
- 0.52 hPa
- Conclusions:
- The vapour pressure of the test item was calculated using the dynamic method in accordance with test guideline EU A.4 and OECD guideline 104 (2006).
The vapour pressure was calculated by extrapolation of measured vapour pressure data for 20 ̊C (VP = 0.09 hPa), 25 ̊C (VP = 0.13 hPa) and 50 ̊C (VP = 0.52 hPa). - Executive summary:
EU Method A.4. – The vapour pressure of the test item was determined utilising the Dynamic method (vapour–liquid equilibrium). The procedure employed was designed to be compatible with Method A.4. Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008.
The vapour pressure of the test item was measured across a temperature range of 132.5 to 176.8 °C. Values measured across this range showed a good linear response. The test item vapour pressure at 20 °C, 25 °C and 50 °C was extrapolated from a regression of measured values.
The vapour pressure of the test item has been determined to be 0.09 hPa at 20.0 °C.
