Scope

This standard specifies the constant potential electrolysis method for the determination of sulfur dioxide in waste gas from fixed pollution sources. This standard is applicable to the determination of sulfur dioxide in waste gas from stationary pollution sources. The detection limit of this standard method is 3mg/m3, and the lower determination limit is 12mg/m3.
