scope:

This International Standard specifies the principle, the essential performance criteria and QA/QC procedures of an automatic method for measuring total volatile organic compounds (TVOC) content in waste gases of stationary sources, using non-dispersive infrared absorption (NDIR) analyser equipped with a catalytic converter which oxidises VOC to carbon dioxide. This method is suitable for the measurement of TVOC emissions from non-combustion processes. This method allows the continuous monitoring with permanently installed measuring systems as well as intermittent measurements of TVOC emissions. This method has been tested on field operation for painting and printing processes, where TVOC concentrations in the waste gases were up to about 600 mg/m3.
