A plot of log10(vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 1 gives the following statistical data using an unweighted least squares treatment.
Slope -3.94 x 103
Standard deviation in slope 101
Intercept 14.1
Standard deviation in intercept 0.378
The results obtained indicate the following vapor pressure relationship:
Log10(Vp (Pa)) = -3.94 x 103/temp(K) + 14.1
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of 0.924.

A plot of log10(vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 4 gives the following statistical data using an unweighted least squares treatment.
Slope -4.68 x 103
Standard deviation in slope 42.6
Intercept 16.8
Standard deviation in intercept 0.159
The results obtained indicate the following vapor pressure relationship:
Log10(Vp (Pa)) = -4.68 x 103/temp(K) + 16.8
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of 1.08.

Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of the test item has been determined to be 10 Pa at 25 ºC.
- Executive summary:
The determination was carried out using a procedure designed to be compatible with Method A4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008.
Instrument: Vapor pressure balance.

Discussion
A total of four runs were completed for the main sequence. Equilibrium with regard to vapor pressure was assessed to have been reached over the four runs. Thus all four runs have been used to calculate the definitive vapor pressure value for the test item.
The un-shaded points on Runs 1 and 2 have not been used as they are considered erroneous possible due to external interference (vibration) of the balance.
Conclusion
The vapor pressure of the test item has been determined to be 10 Pa at 25 ºC.
