TS EN ISO/IEC 17025

TS EN ISO/IEC 17025 addresses the general requirements for the competence of testing and calibration laboratories. It sets out a common framework for how laboratories establish technical competence and the supporting management arrangements needed to produce dependable results, including activities that involve sampling.

How testing, calibration and sampling fit together

Testing laboratories determine or verify characteristics of a material, product, or sample. Calibration laboratories establish the relationship between an instrument’s indication and a reference value. Sampling is the selection of a portion of material intended to represent the whole. In practice, these activities are closely linked: result quality depends not only on instruments, but also on the method used, the competence of personnel, environmental conditions, traceability, and the way records are controlled.

What this standard covers in principle

According to the scope, the standard applies to testing and calibration performed using standardized methods as well as methods not covered by standardized methods. In broader technical terms, this means the laboratory must manage method selection, equipment suitability, record keeping, result consistency, and related competence factors in a controlled way. That is a general competence framework, not a claim that this standard itself specifies detailed test steps or numerical limits.

This record refers to a withdrawn edition of the standard. The description therefore explains the technical subject and historical scope of that edition, while current laboratory practice should be checked against the applicable up-to-date version.
