- Key result
- Surface tension:
- 51.2 mN/m
- Temp.:
- 20 °C
- Conc.:
- 5.05 mg/L
- Remarks on result:
- other: mean value
- Conclusions:
- The surface tension was determined to be 51.2 mN.m-1 (mean value) using the ring method.
- Executive summary:
The test is conducted to determine the effect of a compound, on the free surface enthalpy per unit surface area of water.
The test is conducted in accordance to EU Regulation (EC) 440/2008, Annex Part A test A.5and OECD Test Guideline 115.
The surface tension was determined to be 51.2 mN.m-1 (mean value) using the ring method therefore the test item is surface active.
