Results and discussion
Vapour pressure
- Key result
- Temp.:
- ca. 25 °C
- Vapour pressure:
- ca. 5.4 Pa
Any other information on results incl. tables
Recorded temperatures, mass differences and the resulting calculated values of vapor pressure are shown in the joint document KS95WT.
A total of 6 runs were completed for the main sequence. The values of vapor pressure at 25 °C has been extrapolated from each graph. (see table 7 of the
KS95WT document).
Equilibrium with regard to vapor pressure was assessed to have been reached over these 6 runs. Thus all 6 runs have been used to calculate the definitive vapor pressure value for the test item.
Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of the test item has been determined to be 5.4 x 10E-7 Pa at 25 ºC.
- Executive summary:
The vapor pressure of Mephtamin-HCL has been determined to be 5.4 x 10E-7 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.
