Reference
Validity criteria for the measurement of the surface tension:
| Target condition according to guideline OECD 115: | Actual condition according to the study: | Validity criteria met: |
| A solution of the substance is prepared in distilled water. The concentration of this solution should be 90 % of the saturation solubility of the substance in water; when this concentration exceeds 1 g/ L, a concentration of 1 g/ L is used for testing. | The test substance was determined to be miscible with water at any ratio (see "Water solubility"). A concentration of 1 g/ L was used for testing. | Yes |
| The measurement shall be made at approximately 20 °C and shall be controlled to within ± 0.5 °C. | The test temperature was 20 °C ± 0.5 °C. | Yes |
| The measurement results: individual readings, their arithmetic mean and the corrected mean; concentration of the solution should be stated. | The results are stated in sufficient detail (a correction factor (Harkins & Jordan) has already been accounted in the individual results). | Yes |
Description of key information
