Materials and methods

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

Applicant's summary and conclusion

Conclusions:
The vapour pressure of LCE07101 is defined as the highest value of the P 25°C of the substances present in the test item.
The vapour pressure at 25°C of LCE07101 is equal to 6.66 x 10-5 Pa.
Executive summary:

Type of method: gas saturation method.

The vapour pressure is defined as the highest value of the P 25°C of the substances present in the test item.

The vapour pressure at 25°C of the product is equal to 6.66 x 10-5 Pa.
