ISO 11843-4:2003涉及在不考虑ISO 11843-2中线性校准曲线假设以及剩余标准偏差和净状态变量值之间的某些关系的情况下，对测量方法检测能力的评估 ISO 11843-4:2003没有估计最小可检测值，而是提供了判断最小可检测值是否小于净状态变量给定水平的标准，以及测试该标准符合性的基本实验设计。

ISO 11843-4:2003 deals with the assessment of the capability of detection of a measurement method without the assumptions in ISO 11843-2 of a linear calibration curve and certain relationships between the residual standard deviation and the value of the net state variable Instead of estimating the minimum detectable value, ISO 11843-4:2003 provides a criterion for judging whether the minimum detectable value is less than a given level of the net state variable, and the basic experimental design for testing the conformity of this criterion.
