ÖNORM EN 13526

This European Standard specifies a set of minimum performance requirements for an instrument using flame ionisation detection, together with procedures for its calibration and operation, for the measurement of the mass concentration of total gaseous organic carbon (TOC) in flue gases. This European Standard is suitable for the measurement of gaseous or vapour phase TOC emissions from Solvent Using Processes. NOTE 1 See Council Directive 1999/13/EEC. The results obtained using this standard are expressed in milligrams per cubic metre as total carbon (mg/m3). This standard is suitable for the measurement of concentrations from 20 mg/m3 to 500 mg/m3 but can be used at lower concentrations. NOTE 2 By its nature a flame ionisation detector (FID) can also be used to measure higher concentrations. The method specified in this European Standard can be used as a reference method or, with suitable minimum operational requirements, for continuous monitoring. It can also be used for the calibration of automated measuring systems. An indication of the uncertainty of the measurement is shown in annex A.
