Accuracy (trueness and precision) of measurement methods and results - Basic methods for the determination of the trueness of a standard measurement method
What is ISO 5725 ‑ 4 about?
ISO 5725 is a series of international standards on measurements that discusses the procedures and specifications to keep a check on the bias of different methods. ISO 5725 ‑ 4 is the fourth part of the ISO 5725 multi-series . ISO 5725 ‑ 4 specifies basic methods for estimating the bias of a measurement method and the laboratory bias when a measurement method is applied, provides a practical approach of a basic method for routine use in estimating the bias of measurement methods and laboratory bias, brief guidance to all personnel concerned with designing, performing or analysing the results of the measurements for estimating bias.
ISO 5725 ‑ 4 applies when the measurement method has been standardized and all measurements are carried out according to that measurement method .
