UpcomingAccuracy (trueness and precision) of measurement methods and results—Part 4:Basic methods for the determination of the trueness of a standard measurement method
测量方法与结果的准确度（正确度与精密度） 第4部分：确定标准测量方法正确度的基本方法
Application Summary AI generated
This standard provides statistical methods for assessing the trueness (bias) of a standard measurement method by determining the systematic error relative to a reference value. It is applied in laboratory testing and quality control across industries such as manufacturing, chemistry, and food testing, where verifying the accuracy of standardized analytical procedures is required. The standard is used when conducting interlaboratory studies to evaluate how closely a measurement method's results agree with an accepted reference value.
