Determination of Mass Concentration of Sulfur Dioxide (SO2) (TS ISO 7935)

The ISO 7935 standard published by the International Standards Organization (ISO) applies to extractive and non-extractive automatic sulfur dioxide measurement methods. This standard describes four key performance characteristics: detection limit, interference effect, response time, and integrated performance. The standard appendices list key performance specifications (Annex A) and additional performance specifications (Annex B).

This standard has also been published by TSE in our country with the following title: TS ISO 7935 Point source emissions - Determination of mass concentration of sulfur dioxide - Performance characteristics of automatic measurement methods.

In short, the standard provides a complete set of performance characteristics values ​​for automatic measurement systems for the continuous measurement of sulfur dioxide mass concentrations in stationary source emissions. If the performance characteristics of the automatic measurement system are listed according to the table in the standard, this ensures that the automatic measurement system is reliable and gives satisfactory continuous results.

The automatic measurement system can be calibrated with calibration gases by applying the manual method described in this standard or by applying a previously validated automatic measurement system using a different detection principle.

In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests carried out in this context, there are services for the determination of the mass concentration of sulfur dioxide (SO2) (TS ISO 7935).
