ISO 16017-1:2000

Overview

ISO 16017-1:2000 establishes standardized procedures for the sampling and analysis of volatile organic compounds (VOCs) in air, specifically focusing on pumped sampling using sorbent tube, thermal desorption, and capillary gas chromatography. This international standard is applicable to a wide range of environments including indoor, ambient, and workplace atmospheres, as well as emissions testing from materials in various scales of test chambers. By providing guidance on equipment selection, calibration, and quality control, ISO 16017-1 provides a reliable framework for quantifying VOC levels and supporting air quality assessments.

Key Topics

• Sampling Technique: Use of low flowrate personal sampling pumps in combination with appropriately selected sorbent tubes for the effective collection of airborne VOCs.
• Applicability: Suitable for a broad spectrum of VOCs, including but not limited to hydrocarbons, halogenated hydrocarbons, esters, glycol ethers, ketones, and alcohols.
• Sorbent Selection: Recommends different sorbents based on compound type, volatility, and other properties. Guidance is provided for selecting the optimal sorbent material, with practical advice on their range of applicability.
• Concentration Range: Enables quantitative measurement of airborne VOCs over a range from approximately 0.5 µg/m³ up to 100 mg/m³ per compound, contingent upon the capacity and characteristics of the chosen sorbent.
• Breakthrough and Recovery: Discusses issues such as breakthrough volumes, artifact formation, and partial recovery for certain compounds, and provides strategies to mitigate these effects (e.g., use of back-up sorbent tubes).
• Lab Procedures: Covers requirements for pump calibration, sample tube conditioning, analytical calibration, desorption procedures, and quality control measures.

Applications

ISO 16017-1:2000 is highly valuable in a range of practical scenarios, where accurate VOC analysis is critical:

• Workplace Air Monitoring: Ensures compliance with occupational exposure limits by measuring personal exposure and ambient concentrations of VOCs in industrial or office environments.
• Indoor and Ambient Air Quality: Facilitates studies and regulatory compliance related to the presence of VOCs commonly found in building materials, consumer products, or external pollutants.
• Emission Testing: Supports assessment of VOC emissions from construction materials, furnishings, or chemical products in both small and full-scale environmental chambers.
• Environmental and Health Research: Provides a standardized approach for research institutions and laboratories conducting investigations into air quality impacts and source identification of VOCs.
• Regulatory and Compliance Testing: Used by accredited laboratories and compliance bodies to meet national and international legal requirements for air sampling and reporting.

Related Standards

Several other international standards complement or reference the procedures and principles of ISO 16017-1, ensuring interoperability and broad application across the field of air quality analysis:

• ISO 16017-2: Focuses on diffusive sampling of VOCs using similar analytical principles.
• ISO 5725-1 / ISO 5725-2: Outline principles for accuracy, trueness, and precision in measurement methods, relevant to quality assurance in VOC analysis.
• ISO 6141 / ISO 6145 Series / ISO 6349: Provide standardized methods for preparation and certification of calibration gases crucial for instrument calibration and method validation.
• EN 1076: Defines requirements and test methods for pumped sorbent tubes used in workplace atmosphere monitoring.

By adhering to the procedures set out in ISO 16017-1:2000, stakeholders can achieve reliable, reproducible, and internationally recognized results in VOC sampling and analysis, promoting safety, health, and environmental protection across varying applications.
