Description (English):

This part of ISO 17190 specifies a method for determining the content of respirable particles in polyacrylate (PA) superabsorbent powders. NOTE Commercial polyacrylate superabsorbent powders consist of particles averaging 400 μm to 800 μm in diameter, which are much larger than the maximum size for respirable particles of approximately 10 μm. Due to the production process, very low amounts of respirable particles may be present in commercial superabsorbent powders.

Abstract

Overview

ISO 17190-11:2001 specifies a laboratory method for determining the content of respirable particles in polyacrylate (PA) superabsorbent powders used in urine‑absorbing aids for incontinence. The standard addresses the potential presence of very small particles (defined as < 10 µm) that can be generated during production even though commercial superabsorbent particles typically average 400–800 µm. The method combines sieve fractionation and laser‑light scattering (diffraction) particle sizing on a wet dispersion.

Key topics and requirements

Scope and definition
- Targets polyacrylate superabsorbent powders; a respirable particle is defined as < 10 µm.
Sampling and conditioning
- Representative sampling procedures (remove top layer, airtight container); test conditioning per ISO 187 (preferred 23 ± 2 °C, 50 ± 10 % RH).
- Test portion: 100 g (using ISO 8213 sampling techniques or a sample divider).
- Safety note: use respiratory protection or fume hood for sample amounts > 10 g.
Separation and preparation
- Sieve the bulk sample through stainless steel screens of 500 µm, 250 µm and 106 µm; collect fraction passing 106 µm.
Particle measurement
- Analyze the
