标准范围

该程序适用于最低30 mg/m3的取样周期，取样周期通常为30 min。当质量浓度大于2000 mg/m3时，通过取样序列的被调查废气体积为30升。给出了已知对滴定读数有影响的物质。所有浓度均基于温度为273.1 K、压力为101.3 kPa的干气。

The procedure is applicable from a minimum of 30 mg/m3 by reference to sampling periods of mormally 30 min. At mass concentrations greater than 2 000 mg/m3 the volume of the waste gas under investigation passed through the sampling train is 30 litres. Substances, which are known to have an effect on the titration reading are given. All concentrations are based on dry gas at a temperature of 273,1 K and a pressure of 101,3 kPa.
