本文件规定了单一实验室验证或协同试验验证的元素分析方法和饲料中化学物质的性能标准。包括方法验证相关参数的术语和定义。提供性能要求和特性。本文件可作为指导: - 评估新的欧洲标准方法的质量; - 确认已经发布的欧洲标准适用于其他分析物浓度或基质的范围的扩展; - 评估单一验证方法的适用性

This document specifies performance criteria for the selection of single-laboratory validated or collaborative-trial validated methods of analysis of elements and their chemical species in feed. The terms and definition of the relevant parameters for method validation are included. The performance requirements and characteristics are provided. This document may serve as a guide: - to assess the quality of new European Standard methods under validation; - to review the quality of previous collaborative trials; - to confirm the extension of the scope of an already published European Standard applied to other analyte concentrations or matrices; or - to evaluate the fitness-for-purpose of single-validated methods. The performance criteria can apply to methods dedicated to the determination of heavy metals, trace elements, major elements and minerals.
