Applicant's summary and conclusion

Conclusions:

The surface tension of the test article was determined to be :

72.4 mN/m (63% saturated)
72.3 mN/m (42% saturated)
72.2 mN/m (21% saturated)

Executive summary:

In a general physico-chemical properties study (13193), the surface tension of the test material was determined to be 72.4 mN/m, 72.3 mN/m and 72.2 mN/m for 63%, 42% and 21% saturated solutions, respectively, according to Method A5 of EEC Directive 84/449 and OECD Guideline 115.
