Materials and methods

Test guideline
Qualifier:
no guideline required
Principles of method if other than guideline:
The test item is a mixture of substances showing presumably low vapour pressoure properties. Using defined technics (e.g. effusion method, gas saturation method) would certainly conduct to flimsy results. The vapour pressure can then be obtained by calculation. The obtained value is a trend of the value of the vapour pressure.
