SIST EN 13528-3:2004

Overview

EN 13528-3:2003 (CEN) is the European guide for the selection, use and maintenance of diffusive samplers used to measure ambient air quality. Part 3 of the EN 13528 series provides practical guidance for deploying passive/diffusive samplers to determine concentrations of gases and vapours in ambient atmospheres. This guidance supports reliable field monitoring, consistent results, and effective measurement programmes for outdoor air quality assessment.

Key topics and requirements

The standard focuses on practical and quality-related aspects rather than prescribing single technical procedures. Major topics covered include:

• Sampler selection criteria - guidance on choosing appropriate diffusive (passive) samplers for specific gases, vapours and concentration ranges.
• Sampling strategy - considerations for site selection, exposure duration, and spatial coverage to achieve representative ambient monitoring.
• Deployment best practices - instructions to optimize sampler orientation, mounting height, sheltering from weather and avoiding local interference sources.
• Handling and storage - recommendations for pre-conditioning, storage and transport to minimise contamination and preserve sorbent performance.
• Maintenance and inspection - routine checks, replacement intervals and criteria to ensure sampler integrity and performance in prolonged monitoring campaigns.
• Quality assurance and control (QA/QC) - approaches for blank checks, field duplicates, laboratory traceability and documentation to support data validity.
• Environmental limitations - factors such as temperature, humidity and wind that can affect diffusive uptake rates and how to account for them in planning and interpretation.

Practical applications

EN 13528-3 is intended to improve the reliability and comparability of passive sampling in a range of ambient air monitoring applications:

• Long-term urban and regional air quality surveys for regulatory or research purposes
• Screening studies for pollutant hotspots and exposure mapping
• Community-led or low-cost monitoring projects using passive samplers
• Baseline studies prior to development projects or remediation work

Who should use this standard

• Environmental consultants and air quality practitioners
• Local authorities and regulatory bodies conducting ambient monitoring
• Laboratories analysing passive sampler media
• Researchers and NGOs performing field sampling and exposure assessments
• Manufacturers and suppliers of diffusive (passive) samplers

Related standards

Part 3 is the guidance element of the EN 13528 series for diffusive samplers. Users should consider other parts of the series and national guidance when implementing a full measurement programme to ensure compliance and data quality.
