TS EN ISO/IEC 17025

TS EN ISO/IEC 17025 is the key standard addressing the technical competence of testing and calibration laboratories and the reliable operation of laboratory activities. It sets out the general requirements laboratories need in order to work impartially, produce consistent results, and demonstrate overall competence.

Three core dimensions of laboratory competence

The standard treats laboratory performance as a system rather than as a matter of equipment or staff alone. Impartiality means results are produced without inappropriate influence or conflict of interest; competence refers to the suitability of technical knowledge and practical ability; and consistent operation is about maintaining a dependable and repeatable approach across similar activities. In general technical terms, these three elements form the basis of confidence in testing and calibration results.

What it means for testing and calibration work

Testing laboratories carry out measurement, observation, or verification activities on items or samples, while calibration laboratories establish the relationship between values indicated by a measuring instrument and reference values. This standard provides a common framework for both types of laboratories, helping align the management of methods, the traceability of results, and the reliability of service. It covers general requirements for laboratory operation; the detailed technical methods depend on the specific field of activity.

As a result, TS EN ISO/IEC 17025 is an important reference for organizations that purchase laboratory services, bodies involved in conformity assessment, and users who rely on measurement-based decisions. The standard helps explain not what a laboratory measures, but the level of quality and confidence with which it carries out testing and calibration services.
