The method described in this European Standard determines the concentration of chlorinated compounds in a flue gas that - after passage of the sampling system including a particle filter - give Cl- ions in the absorption solution. This Standard Reference Method has been evaluated during field tests on waste incineration. The method applies to waste gases in which chlorides concentration expressed as HCl may vary between1 mg m-3 and 5 000 mg m-3 under normal pressure and temperature conditions (see Note 1), and according to emission limit values laid down, for example, in the Council Directive 2000/76/EC on waste incineration plants.NOTE 1The limit values of this European Standard are expressed in mg HCl/m3, on dry basis, at the reference conditions of 273 K and 101,3 kPa and at the reference O2 concentration. NOTE 2The required uncertainty results from the capacity of the method tested in the field (Annex D) and in the laboratory (see performance characteristics in Tables 1 and 2 and Annex C).
