Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Principles of method if other than guideline:
- This study has been performed in according to the OECD Guideline for Testing of Chemicals
No. 104 "Vapour Pressure Curve",
As mentioned in the OECD Guideline for Testing of Chemicals No. 104 p. 2,5,6, several methods
are applicable to the entire range of vapour pressures. However, in the lowest range the
gas saturation method is recommended. We are using in this lowest vapour pressure range
the thermobalance method instead of the gas saturation method. This thermobalance method
has been developed in our laboratory (see B.F. Rordorf, A. Geoffroy, M. Szelagiewicz,
and E. Marti, "Vapour Pressure Methods for Industrial Applications" in Thermal Analysis,
Proc. 6th Int. Conf. Therm. Anal. Vol. I, ed. H,G. Wiedemann, Birkhauser, Basel, 1980, p. 313)
The validity of the thermobalance method was tested with benzoic acid. The agreement with
literature was extremely good (e.g, OECD Guideline No. 104, p. 4). - GLP compliance:
- yes
- Type of method:
- static method

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
