DIN CEN/TS 16450*DIN SPEC 33967:2013-08

This document lays down the (minimum) performance requirements and test procedures for the selection of appropriate AMS for particulate matter (type approval). This includes the evaluation of its equivalence with the reference method. Further, this document describes (minimum) requirements for ongoing quality assurance - quality control (QA/QC) of AMS deployed in the field. These requirements are necessary to ensure that uncertainties of measured concentrations are keptwithin the required limits during extended periods of continuous monitoring in the field, and include procedures for maintenance, calibration and control checks. Additional procedures are described that determine whether an instrument's equivalence to the reference method is maintained through possible pollution climate changes, over periods longer than 5 years. Lastly, this document describes requirements and procedures for the treatment and validation of raw measurement data that are to be used for the assembly of daily or yearly average concentration values. Experiences with existing methods for data treatment and validation - for similar AMS - have learned that the different ways of data treatment and validation applied may lead to significant differences in reported results for similar datasets.
