PD CEN/TS 17021 describes a method for sampling and determining the concentration of gaseous sulphur dioxide (SO2) emissions from stacks. This method is based on instrumental techniques.
PD CEN/TS 17021 is applicable to both periodic measurements and the calibration of automated measuring systems permanently installed on stacks, for regulatory or other purposes.
PD CEN/TS 17021 on mass concentration of sulphur dioxide is relevant to:
An instrumental method is used to measure the properties of the analyte by performing chemical analysis.
PD CEN/TS 17021 specifies the characteristics to be determined and the performance criteria to be fulfilled by portable automated measuring systems based on instrumental technique.
PD CEN/TS 17021 describes methods described in a written procedure containing the means and procedures required to sample and analyse, such as the field of application, principle or reaction, definitions, equipment, procedures, results, other requirements, and measurements.
Overall, PD CEN/TS 17021 specifies the procedures for determining and sampling sulphur dioxide using instrumental techniques emitted to the atmosphere from ducts and stacks that reduce pollution caused by harmful gases.
