Urine-absorbing aids for incontinence - Test methods for characterizing polymer-based absorbent materials - Part 9: Gravimetric determination of density

This part of ISO 17190 specifies a method for determining the apparent density of polyacrylate (PA) superabsorbent powders.

This method has been tested in the range 0,67 g/ml to 0,72 g/ml (see annex A), but it is expected to be applicable to a wider range.
