DIN EN 14662-3:2013-08

The draft European Standard EN 14662-3 specifies a semi-continuous measurement method for the determination of the concentration of benzene present in ambient air based on automated sampling and analysis by gas chromatography. It describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate automated gas chromatograph (GC) by means of type approval tests. It also includes the evaluation of the suitability of an analyser for use in a specific fixed site so as to meet the data quality requirements as specified in Annex I of Directive 2008/50/EC and requirements during sampling, calibration and quality assurance for use. The Standard is directed towards test houses and laboratories that perform type-approval testing of benzene analysers and monitoring networks performing the practical measurements of benzene in ambient air.
