This document provides a test method that determines the capacity of polyacrylate superabsorbent powders to absorb saline solution under a specified enclosing pressure.
Abstract
Overview
ISO 17190-7:2020 specifies a to determine the capacity of used in urine‑absorbing aids for incontinence to absorb a 0.9 % saline solution . The method quantifies absorption against pressure (AAP) by weighing a defined powder specimen before and after immersion under controlled pressure and time (60 minutes). This standard is part of the series on urine‑absorbing aids and provides repeatable lab procedures for material characterization and quality control.
