A plot of Log10(vapour pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 1 gives the following statistical data using an unweighted least squares treatment.
Slope -4097.343
Standard deviation in slope 296.623
Intercept 11.284
Standard deviation in intercept 0.912
The results obtained indicate the following vapour pressure relationship:
Log10(Vp (Pa)) = -4097.343/temp(K) + 11.284
The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of -2.459.

A plot of Log10(vapour pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 5 gives the following statistical data using an unweighted least squares treatment.
Slope -3484.402
Standard deviation in slope 229.295
Intercept 9.399
Standard deviation in intercept 0.705
The results obtained indicate the following vapour pressure relationship:
Log10(Vp (Pa)) = -3484.402/temp(K) + 9.399
The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of -2.288.

Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test item has been determined to be 4.2 x 10e-3 Pa at 25ºC.
- Executive summary:
INTRODUCTION
Hazardous physico-chemical properties of the test item have been determined.
Methods employed are designed to be compatible with those specified in 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.
