Incontinence particle testing standards are published by ISO. This includes the ISO 17190 series for Urine-absorbing aids for incontinence, which covers the Test method for determination of the particle size distribution by sieve fractionation, gravimetric determination of absorption against pressure, and Determination of content of respirable particles.
This document specifies a test method for measuring particle size distributions up to 850 µ of cross-linked polyacrylate superabsorbent powders. It applies only to measurements made where sieve shaking is used for the separation. Tapping equipment is not expected to deliver the same results. This method is applicable to powdered polymeric superabsorbent materials that are free-flowing under the specified test conditions.
This document provides a test method that determines the capacity of polyacrylate superabsorbent powders to absorb saline solution under a specified enclosing pressure.
This part of ISO 17190 specifies a method for determining the content of respirable particles in polyacrylate (PA) superabsorbent powders.
