Overview
EN ISO 16000-5:2007 (ISO 16000-5:2007) - “Indoor air - Part 5: Sampling strategy for volatile organic compounds (VOCs)” is a CEN-endorsed ISO standard that provides guidance for planning measurements of volatile organic compounds in indoor environments. It focuses on designing a robust sampling strategy because poor planning can introduce greater uncertainty than the analytical method itself. The document is intended as an aid to practitioners who need representative, defensible VOC indoor-air data.
Key topics
- Definition and classification of VOCs - overview of volatility classes (VVOC, VOC, SVOC) and relevance to sampling media and analysis.
- Sources and occurrence - typical indoor VOC sources (building products, furniture, occupants, activities, ambient air) and implications for variability.
- Measurement techniques - considerations for short-term and long-term measurements and links to active and diffusive sampling methods.
- Sampling and measurement planning - systematic workflow covering:
- Measurement objectives and recording environmental conditions
- Timing of sampling (time of day, activities)
- Duration and frequency of sampling
- Selection of sampling locations within rooms or buildings
- Presentation of results and assessment of measurement uncertainty
- Quality assurance and documentation
- Informative annexes - examples of VOCs commonly found in indoor air and a protocol to record activities and boundary conditions during sampling.
Practical applications
- Developing a sampling campaign to assess indoor air quality (IAQ) in offices, schools, homes, or public buildings.
- Designing monitoring programs to verify remediation success after contamination or renovation.
- Informing decisions on ventilation improvements, product selection, or exposure mitigation.
- Standardizing sampling strategy for research studies, compliance checks, and forensic IAQ investigations.
Who should use this standard
- Environmental and indoor air quality consultants
- Industrial hygiene and occupational health professionals
- Building managers, facility operators, architects and HVAC engineers
- Accredited laboratories and field technicians performing VOC sampling
- Regulators and policy makers setting IAQ monitoring requirements

- ISO 16000-6: Determination of VOCs by active sampling (Tenax TA, thermal desorption, GC-MS/FID)
- ISO 16000-8: Determination of local mean ages of air (ventilation characterization)
- ISO 16017-1 and ISO 16017-2: Sampling and analysis of VOCs by sorbent tubes (pumped and diffusive)
Using EN ISO 16000-5:2007 as part of an ISO 16000-compliant program helps ensure VOC sampling plans are scientifically defensible, reproducible and fit for decision-making about indoor air quality.
