Results and discussion
Vapour pressure
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- > 0.001 Pa
- Remarks on result:
- not determinable because of methodological limitations
- Remarks:
- The value of –1500 K is an in-house value and is the shallowest slope observed whilst determining the vapor pressure on a wide range of samples using the vapor pressure balance method. Extrapolation to 25 ºC gave a vapor pressure of 1.09 x 10-3 Pa which has been taken as a maximum for this test item.
Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of the test item has been determined to be less than 1.1 x 10^-3 Pa at 25 °C
- Executive summary:
The vapor pressure of the test item has been determined to be less than 1.1 x 10-3 Pa at 25 °C, using the vapor pressure balance method, designed to be compatible with Method A4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.
