Results and discussion
Vapour pressure
- Key result
- Test no.:
- #10
- Temp.:
- 90 °C
- Vapour pressure:
- 0.033 Pa
Any other information on results incl. tables
Run 10 from 10 was chosen because the sample had been under vacuum for the longest period prior to this run and so degassing would have been the most complete. The reading at 90 ºC (363.15 K) was chosen because this is the data point which gives the highest estimated vapor pressure at any given temperature when a slope of –1000 K is imposed upon it.
Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of the test item has been determined to be less than 8.3 x 10-3 Pa at 25 ºC.
- Executive summary:
The vapor pressure of the test item has been determined to be less than 8.3 x 10-3 Pa at 25 °C, using the vapor pressure balance method, designed to be compatible with Method A.4 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.
