ISO 13913:2014规定了在萃取和气相色谱分析以及质谱检测后，测定污泥、处理过的生物废物和土壤中选定邻苯二甲酸盐的方法。 该方法适用于测定所选邻苯二甲酸酯的最低质量含量为0.1 mg/kg至0.5 mg/kg（以干物质表示），具体取决于单个物质。 除了异构混合物，例如DiNP（邻苯二甲酸二异壬酯），本方法对其他邻苯二甲酸酯的适用性不排除在外，但需在每种情况下进行验证。

ISO 13913:2014 specifies a method for the determination of selected phthalates in sludge, treated biowaste, and soil, after extraction and gas chromatographic analysis with mass spectrometric detection. The method is applicable for the determination of selected phthalates at the lowest mass content of 0,1 mg/kg to 0,5 mg/kg (expressed as dry matter), depending on the individual substance. The applicability of the method to other phthalates is not excluded except the isomeric mixtures, e.g. DiNP (Di-isononylphthalate), but is to be verified in each case.
