本技术规范中描述的方法适用于测定饮用水中选定的植物处理剂及其一些主要降解产物（代谢物），经验证的报告限值约为（见表1中的示例）。该方法可以扩展到包括其他物质和地下水，前提是该方法针对每种情况进行了验证。 根据实验室间试验（1992年）时的知识，选择了表1和表A.2中的植物处理剂和主要降解产物。附件A中给出了一些其他物质的数据。

The method described in this Technical Specification is applicable to the determination of selected plant-treatment agents and some of their main degradation products (metabolites) in drinking water, with a validated reporting limit of about (see examples in Table 1). The method may be extended to include additional substances and ground water, provided the method is validated for each individual case. The selection of the plant-treatment agents and main degradation products in Table 1 and Table A.2 has been made according to the knowledge at the time of the interlaboratory trial (1992). Data for some other substances are given in annex A.
