2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

according to guideline

Guideline:

EU Method A.5 (Surface Tension)

Deviations:

no

GLP compliance:

yes

Type of method:

OECD harmonised ring method

Surface tension:

68.8 mN/m

Temp.:

20 °C

Conc.:

1 000 mg/L

Remarks on result:

other: average of final three values

Remarks:

corrected value

- Result first measurement: 68.84 mN/m

- Result second measurement: (after 30 minutes waiting/age of test solution 27 h. 30 min.): 68.91mN/m

Conclusions:

The surface tension as corrected value is 68.84 mN/m measured at 20 °C. The concentration of the test solution was 1.0 g/L.

Executive summary:

The study was performed according to guideline A.5 for detennination of the surface tension, EG-guideline 92/69 by the OECD ring method at 20 °C. The concentration of the test solution was 1.0 g/L. The calibration factor (Phi b) of pure water at 20 °C was 0.9481. Corrected results of the surface tension for the first and second measurement (after 30 minutes waiting) were 68.84 mN/m and 68.91 mN/m. The surface tension as corrected value was 68.84 mN/m (average of the final three values).

Description of key information

The surface tension as corrected value is 68.84 mN/m measured at 20 °C. The concentration of the test solution was 1.0 g/L.

Key value for chemical safety assessment

in mN/m at 20°C and concentration in mg/L:

68.84

Additional information

The corrected surface tension of 68.84 mN/m is the average of the final three values. The calibration factor (Phi b) of pure water at 20 °C was 0.9481.
