标准摘要
[中文适用范围]： 本国际标准规定了采用高效液相色谱（HPLC）测定肥料中异丁二烯二脲（IBDU）、巴豆二脲（CDU）（方法A）和亚甲基脲低聚物（MU）（方法B）的方法。 该方法适用于所有不含干扰有机化合物的肥料。 [外文原描述]： ISO 25705:2016 specifies methods for the determination of isobutylidene diurea (IBDU), Crotonylidene diurea (CDU) (method A) and methylene-urea oligomers (MU) (method B) in fertilizers using high-performance liquid chromatography (HPLC). The method is applicable to all fertilizers which do not contain interfering organic compounds.
