Participation in proficiency testing schemes is generally recognized as an important part of quality control in analytical chemistry. The design and conduct of proficiency testing schemes is therefore a matter of great importance. A proficiency testing scheme should: a) cover a broad concentration range of the substance of interest; b) enable the detection and estimation of each laboratory's systematic errors; c) enable estimation of each laboratory's random error; d) provide each laboratory with a rank or score, and e) present the evaluation of each round to the participating laboratories in a comprehensible way, e.g. in a report with carefully designed text, tables and figures. This paper presents the design of the Danish external quality assessment scheme (DEQAS), which is based on the method evaluation function concept.
参与能力验证计划通常被认为是分析化学质量控制的重要组成部分。因此，能力验证计划的设计与实施是非常重要的事情。一个能力验证计划应：a) 涵盖所关注物质的广泛浓度范围；b) 能够检测和估计每个实验室的系统误差；c) 能够估计每个实验室的随机误差；d) 为每个实验室提供一个排名或分数，以及e) 以一种可理解的方式向参与实验室呈现每一轮的评估结果，例如在一份精心设计文本、表格和图表的报告中。本文介绍了基于方法评估函数概念的丹麦外部质量评估计划（DEQAS）的设计。
