Overview

ISO 17190-5:2020 specifies a laboratory test method for measuring the free swell capacity of polyacrylate superabsorbent powders (SAPs) used in urine-absorbing aids for incontinence. The method uses gravimetric measurement in 0.9% saline to determine how much fluid a known mass of polymer absorbs under free-swelling conditions. This standard is part of the ISO 17190 series covering polymer-based absorbent materials for incontinence products.

Key topics and requirements

Scope: Determination of free swell capacity (mass fraction, g/g) of polyacrylate superabsorbent powders in saline.

Test fluid: 0.9% sodium chloride solution prepared with Grade 3 water (ISO 3696); typical conductivity ≈ 1600 μS/m at 25 °C; recommended test temperature (23 ± 2) °C.

Sample portion: 0.180–0.220 g of dry SAP per test specimen, placed in a water-permeable nonwoven “teabag”.

Teabag specification: Non-apertured heat-sealable nonwoven of defined dimensions and properties (example: 60×40 mm to 60×85 mm).

Procedure highlights:

Weigh dry sample (ms), seal in teabag, immerse in saline for 30 minutes.
Remove and hang teabag from a corner for 10 minutes to drip off excess liquid.
Weigh wet teabag (mw); run blanks to correct for bag uptake.

Calculation: Free swell capacity (g/g) computed from the dry mass, wet bag mass and blank average to give absorbed mass per gram of polymer.

Reporting: Include sample ID, method reference (ISO 17190-5:2020), test conditions, equipment, raw and averaged results (g/g), deviations, and any statistical measures.

Safety and quality: Guidance on conditioning (23 ± 2 °C, 45 ± 15 % RH per ISO 187), sample homogenization, and respirable dust precautions (guideline value noted for respirable SAP dust).

Applications and users

Who uses it: R&D laboratories, quality control teams, regulatory testing bodies, and manufacturers of diapers, pads, and other incontinence products.

Practical value:

Establishes consistent, reproducible data for SAP absorption performance in saline/urine-like conditions.
Supports product formulation, comparative benchmarking, QC acceptance criteria, and supplier evaluation.
Helps correlate material performance (free swell capacity) with retention and wearing comfort in end products.
