ISO 17190-1:2001
Urine-absorbing aids for incontinence - Test methods for characterizing polymer-based absorbent materials - Part 1: Determination of pH
This part of ISO 17190 specifies a method for determining the pH of polyacrylate (PA) superabsorbent powders.
This method has been tested in the range of pH 5,92 to pH 6,14 (see annex A), but it is expected to be applicable to a wider range.
