Ambient air quality - Diffusive samplers for the determination of concentrations of gases and vapours - Requirements and test methods - Part 2: Specific requirements and test methods
This standard specifies specific performance requirements and test methods under prescribed laboratory and field conditions for diffusive samplers used for the determination of the concentration of gases or vapours in ambient air. Such requirements apply to all diffusive samplers, irrespective of the physical nature of the rate-controlling process and irrespective of the nature of the sorption process and the analytical determination.
