Materials and methods
Test guideline
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- the surface tension is determined with a LAUDA-Drop volume tensiometer TVT.
Drops are generated using a suitable device. These drops grow as long as their weight is less than their holding force on the capillary. As soon as this weight has reached the same magnitude as the holding force, the drop falls and the volume of the falling drop is measured. The surface tension is then automatically calculated from this volume with the LAUDA-drop volume tensiometer TVT. - GLP compliance:
- no
- Type of method:
- other: Drop-Weight 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.
