ISO/TC 173/SC 3/WG 2 - Urinary absorbing aids

This document provides recommended and other product type names and example pictures of product categories defined in ISO 9999, subclass 09 30, "Absorbing products to contain urine and faeces".

This document provides a test method for determining the sum of residual monomeric sodium acrylate and acrylic acid present in polyacrylate superabsorbent powders as acrylic acid.

This document provides a test method for determining the pH of granular superabsorbent polyacrylates.

This document provides a test method to determine the mass fraction of soluble polymers present in crosslinked polyacrylate superabsorbent powders that can be extracted into saline solution.

This document provides a test method to determine the mass flow rate and bulk density (or apparent density) of polyacrylate superabsorbent powders.

This document provides a test method for the evaluation of mass loss upon heating for cross-linked polyacrylate superabsorbent powders. This method is applicable to powdered polymeric superabsorbent materials that are free-flowing under the specified test conditions. Substances other than water that are volatile in this temperature range will interfere. The onus is on the polymer formulator/producer to decide if such interference is possible and either exclude the method from use, provide an alternative or modify the method accordingly.

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 free swell capacity of polyacrylate superabsorbent powders in saline solution.

This document provides a test method that determines the capacity of polyacrylate superabsorbent powders to absorb saline solution under a specified enclosing pressure.

This document provides a test method for the determination of the fluid retention capacity of polyacrylate superabsorbent powders in saline solution, following centrifugation.

This document provides a test method for measuring the permeability-dependent absorption under pressure (PDAUP) of polyacrylate superabsorbent powder, where permeability is a significant controlling factor under the conditions of the test.

ISO 15621:2017 gives guidelines for evaluating absorbent incontinence aids for urine and/or faeces. It provides a context for the procedures described in other International Standards and published testing procedures. General factors relating to incontinence products and their usage are also addressed.

Gives a method for determining the absorption capacity of the absorbent core of body-worn urine-absorbing aids.

ISO 15621:2011 gives general guidelines on the methodology of evaluating disposable urine-absorbing aids, and provides a context for the procedures described in other International Standards or published testing procedures. These products are also used for faecal incontinence, which is occasionally mentioned.
