BiH standard BAS ISO 5725-1:2024, third edition, is a translation of the English version of ISO 5725-1:2023. The original text of this international standard was prepared by Technical Committee ISO/TC 69, Applications of statistical methods, Subcommittee SC6, Measurement methods and results.

This document introduces conditions, constraints and resources necessary to evaluate a measurement method or results, defines the organizational scheme for the acquistion of trueness and precision data by study, and provides the necessary definitions, a statistical model, and principles for ISO 5725 (all parts). It is not applicable to proficiency testing or production of the reference item that has their own standards (ISO 13528, respectively and ISO Guide 35).

The document is concerned exclusively with measurement methods which yield results on a continuous scale and give a single value as the test result, although if this single value may be the outcome of a calculation from a set of observations.

It defines values which describe, in quantitative terms, the abiliy of a measurement method to give a true result (trueness) or to replicate a given result (precision). Thus, there is a implication that exactly the identical item is being measured, in exactly the same way, and that the measurement process is under control.

This document may be applied to a wide range of test items, including gas, liquids, powders, and solid objects, manufactured or naturally occurring, provided that due consideration is given to any heterogeneity of the test item.

BAS ISO 5725-1:2024 is a translation from English into Bosnian. This BiH standard was prepared by the Technical Committee BAS/TC 38, Metrology and Measurements.
