Run 1
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 -7026.925
Standard deviation in slope 212.789
Intercept 16.320
Standard deviation in intercept 0.533
The results obtained indicate the following vapour pressure relationship:
Log10(Vp (Pa)) = -7026.925/temp(K) + 16.320.
The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of -7.248.

Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test material has been determined to be 1.3 x 10-8 Pa at 25ºC.
- Executive summary:
Method
The vapour pressure was determined using a vapour pressure balance with measurements being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25°C. Testing was conducted using Method A4 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
Conclusion
The vapour pressure of the test material has been determined to be 1.3 x 10-8Pa at 25ºC.
