- Surface tension:
- 25.8 mN/m
- Temp.:
- 20 °C
- Conc.:
- 98 vol%
- Conclusions:
- Under the conditions of the test, the interfacial tension of the test item was determined to be 25.8 mN/m at 20.0 ± 0.5 °C
- Executive summary:
The interfacial tension between the test substance and air was performed on the basis of the ISO guidelines No. 9101:1987 -12 with a drop volume tensiometer and was determined to be 25.8 mN/m at 20.0 ± 0.5 °C
Reference
The determination of the interfacial tension between the test item and air was performed in accordance with the ISO 9101, using the Lauda TVT 2 Drop Volume Tensiometer. The test was performed at a temperature of 20.0 ± 0.5 °C. The test was performed in triplicate.
