Overview
ISO 17191:2026 – Urine-absorbing products for incontinence - Measurement of airborne respirable polyacrylate superabsorbent materials - Determination of dust in collection cassettes by sodium atomic absorption spectrometry is an international standard developed by the International Organization for Standardization (ISO). This standard specifies a test method for determining the quantity of airborne dust originating from polyacrylate (PA) superabsorbent materials used primarily in the manufacturing of hygiene products, such as urine-absorbing aids for incontinent individuals.
The method focuses on measuring sodium content in samples collected from the air using atomic absorption spectrometry (AAS) to establish the concentration of respirable superabsorbent dust particles. The process is designed for use on superabsorbent materials themselves, not on finished products.
Key Topics
- Airborne Polyacrylate Superabsorbent Dust: The standard addresses the quantification of dust generated from PA-based superabsorbent materials that may become airborne during handling or processing.
- Atomic Absorption Spectrometry (AAS): The test method utilizes AAS for sodium analysis, offering high sensitivity within a range of 0.2 µg to 60 µg, with a detection limit around 0.2 µg.
- Use of Collection Cassettes: Air-monitoring cassettes with PTFE filters are employed to capture airborne dust particles from the PA materials.
- Sample Preparation: Emphasizes meticulous cleaning and handling of sampling equipment to avoid sodium contamination, which is essential for ensuring accurate results.
- Calibration and Accuracy: Detailed procedures are included for calibration curves, blank cassette analysis, and result correction to ensure reliability and reproducibility of measurement results.
Applications
- Quality Assurance in Manufacturing: The method is critical for manufacturers of superabsorbent materials used in hygiene products to monitor the control of airborne dust in production facilities, supporting workplace safety and product quality.
- Workplace Safety and Exposure Assessment: Environmental health and safety professionals use this method to assess occupational exposure to respirable superabsorbent dust, helping to maintain safe air quality in manufacturing environments.
- Material Characterization and R&D: Researchers and quality engineers utilize ISO 17191:2026 for material comparison, process validation, and evaluating improvements in production processes that minimize dust emission.
- Compliance and Regulatory Alignment: Adoption of this standard ensures compliance with international best practices concerning dust emissions from superabsorbent materials, potentially aiding in meeting legislative or customer-specific requirements.
Note: The scope of ISO 17191:2026 is limited to analyzing the superabsorbent material itself and is not intended for use with finished incontinence products.
Related Standards
- ISO 17190 Series: These standards provide additional test methods for the characterization of polymer-based absorbent materials used in urine-absorbing aids.
- ISO 3696:1987: Specifies requirements for water quality in analytical laboratory use, referenced for the preparation of reagents within this method.
- Occupational Hygiene Methods: The procedural elements, such as cassette-based air sampling and blank correction, are aligned with recognized occupational hygiene practices for airborne particle measurement.
By implementing ISO 17191:2026, organizations engaged in the production or quality control of polyacrylate superabsorbent powders benefit from standardized, globally recognized procedures for measuring airborne dust, thereby ensuring product safety, workplace health, and regulatory compliance.
