Reading number	Time (minutes) After 15 minutes' thermal equilibration	Measured surface tension (mN/m) Corrected according to Zuiderna and Waters
1	2	70.5
2	6	70.5
3	8	70.5
4	13	70.4
Mean value (mN/m)		70.5
Mean value x calibration factor (mN/m)		71.1

Conclusions:

The surface tension of a 1 g/L solution of tetraammineplatinum(II) hydrogen carbonate was determined to be 71.1 mN/m at 20.3 deg C, and is therefore considered not to be surface active.

Executive summary:

In a guideline study, conducted to GLP, the surface tension of a 1 g/L solution of tetraammineplatinum(II) hydrogen carbonate was evaluated by the ring method. The surface tension was determined to be 71.1 mN/m at a temperature of 20.3 deg C. Tetraammineplatinum(II) hydrogen carbonate is considered not to be surface active.
