Urine-absorbing aids for incontinence. Test methods for characterizing polymer-based absorbent materials. Part 4:Determination of moisture content by mass loss upon heating first edition
适用范围：This part of ISO 17190 specifies a method for determining the mass loss upon heating for cross-linked polyacrylate (PA) superabsorbent powders with a moisture content ranging between 0 % and 5 % by mass. The method is accurate to within ±0,1 %. In general, this method is expected to be applicable to powdered polymeric superabsorbent materials that are free-flowing at temperatures between 15℃ and 150℃. Substances other than water, that are volatile in this temperature range, will interfere.
