Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Calibration:
Measurement of the surface tension of pure water from Apr.20, 2000:
a= 72.75 mN/m, value cited in the literature for the surface tension of water
b= 76.57 mN/m, measured value of the surface tension of water (20.1°C)
calibration factor Phi b = a/b = 0.9501
Correction:
calibration factor * measured surface tension of the testsubstance
0.9501*75.90 mN/m = 72.11 mN/m
Data:
Surface tension (corrected value) [mN/m] |

Additional information
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.
