Urine-absorbing aids for incontinence - Test methods for characterizing polymer-based absorbent materials - Part 10: Determination of extractable polymer content by potentiometric titration

This part of ISO 17190 specifies a method for determining the mass fraction of carboxylate groups of varying chain length present in polyacrylate (PA) superabsorbent powders which are extractable in saline solution.

This method has been tested in the extractable polymer mass fraction range from 5,29 % to 9,00 % (see annex A), but it is expected to be applicable to a wider range.
