Air quality - Determination of the PM10 fraction of suspended particulate matter - Reference method and field test procedure to demonstrate reference equivalence of measurement methods; German version EN 12341:1998
The document describes a reference method for the determination of the PM10 fraction of suspended particulate matter (particles of an aerodynamic diameter smaller than 10 ? as well as a field test procedure which helps to state the equivalence of commercial PM10 measuring devices compared to the reference method. Through the application of this document, the monitoring of air pollution by fine fraction of suspended particulate matter within the framework of the Council Directive 96/62/EC of the European Union on the assessment and control of air quality shall be harmonized.#,,#
