A plot of Log10(vapour pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 6 gives the following statistical data using an unweighted least squares treatment.
Slope -3763.432
Standard deviation in slope 180.537
Intercept 10.551
Standard deviation in intercept 0.555
The results obtained indicate the following vapour pressure relationship:
Log10(Vp (Pa)) = -3763.432/temp(K) + 10.551
The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of -2.072.

Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test item has been determined to be 0.0077 Pa at 25ºC.
- Executive summary:
Introduction
Hazardous physico-chemical properties of the test item have been determined. Methods employed were designed to be compatible with Commission Regulation (EC) No 440/2008 of 30 May 2008, Part A: Methods for the determination of physico-chemical properties and the current OECD Guidelines for Testing of Chemicals.
Method
The vapour pressure was determined using a vapour pressure balance withasurents being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25°C. Testing was conducted using a procedure designed to be compatible with Method A4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 specified in the OECD Guidelines for Testing of Chemicals, 23 March 2006.
Conclusion
The vapour pressure of the test item has been determined to be 7.7 x 10-3Pa at 25ºC.
