《GB/T 15916-2012表面活性剂 螯合剂含量的测定 滴定法》由TC63（全国化学标准化技术委员会）归口，主管部门为中国石油和化学工业联合会。
Scope
This standard specifies the method for determining the content of chelating agents in surfactants. The content of chelating agents does not exceed 2% (mass fraction). This standard is applicable to the determination of ethylenediaminetetraacetic acid (EDTA) and its salts in surfactants. , Before determining the content of other chelating agents, or determining the content of EDTA in the presence of other chelating agents, the applicability of this method should be confirmed,
