标准范围

规定的方法适用于直接测定浓度在5 mg/l和150 mg/l之间的溶解氯化物。通过使用更大容量的滴定管或样品稀释，工作范围可扩展至400 mg/l。由于许多干扰，该方法不适用于低氯化物含量的重污染水。

The method specified is applicable to the direct determination of dissolved chloride in concentrations between 5 mg/l and 150 mg/l. The working range may be extended to 400 mg/l by using a burette of larger capacity or by sample dilution. Due to many interferences the method is not applicable to heavily polluted waters of low chloride content.
