We present a uniform concept for the requirements of reference methods (RMs) used for target-setting in the German external quality assessment (EQA) scheme. It is proposed that the total allowable error (TAE) of the RMs shall be 0.2 times the acceptance limits in the EQA-scheme. From the TAE are derived limits for maximum RM-bias, RM-imprecision, and the number of measurements.
我们针对德国外部质量评估(EQA)计划中用于设定目标的参考方法(RM)的要求提出了一个统一的概念。建议RM的总允许误差(TAE)应为EQA计划中验收限的0.2倍。从TAE推导出最大RM偏差、RM不精密度和测量次数的限值。
