DIN EN 12341
Ambient air - Standard gravimetric measurement method for the determination of the PM₁₀ or PM2,5 mass concentration of suspended particulate matter; German version EN 12341:2014

Title (German)

Außenluft - Gravimetrisches Standardmessverfahren für die Bestimmung der PM₁₀- oder PM2,5-Massenkonzentration des Schwebstaubes; Deutsche Fassung EN 12341:2014


For air quality across the European Union to be assessed on a consistent basis, Member States need to employ standard measurement techniques and procedures. The aim of DIN EN 12341 is to describe a harmonized methodology for monitoring the mass concentrations of suspended particulate matter (PM10 and/or PM2,5 respectively) in ambient air; following Directive 2008/50/EC on ambient air quality and cleaner air for Europe which sets the parameters specific to the assessment of ambient concentration levels of particulate matter in air. In EN 12341 the earlier European Standards EN 12341:1998 and EN 14907:2005 are merged with the aim of harmonize the very similar procedures that are used to measure mass concentrations of both fractions of particulate matter in ambient air. DIN EN 12341 contains - a description of a manual gravimetric standard measurement method for PM10 and/or PM2,5 using sequential samplers or single-filter samplers; - a summary of performance requirements of the method; - requirements for suitability testing of facilities and equipment on initial application of the method; - requirements for ongoing quality assurance/quality control when applying the method in the field; - the assessment of measurement uncertainty of the results; - criteria and test methods for the evaluation of the suitability of filters for application using this method. Particularly, the methods described in DIN EN 12341 are directed towards the representatives of authorities, measuring network operators, measuring institutes, testing laboratories and measuring equipment manufacturers. The standard has been prepared by CEN/TC 264 "Air quality", the secretariat of which is held by DIN, by working group CEN/TC 264/WG15 "Particulate matter (2,5 µm)". The responsible German body is NA 134-04-02 UA "Messen von Partikeln in der Außenluft" ("Measurement of particles in ambient air").
