TS EN ISO/IEC 17025

TS EN ISO/IEC 17025 is the Turkish adoption of the general requirements standard for the competence of testing and calibration laboratories. It addresses the framework used to judge whether a laboratory can produce technically valid results through the combined control of people, methods, equipment, traceability, reporting, and the quality system. The listed edition has been withdrawn, so the description below focuses on the technical subject and the laboratory competence concept rather than on current status.

What laboratory competence means in practice

In testing and calibration work, competence is more than simply performing a measurement or test. It is the ability to generate results that are technically sound, consistent, and traceable. Core concepts in this field include measurement uncertainty, calibration traceability, method suitability, equipment verification, personnel competence, and record integrity. The ISO/IEC 17025 family provides a common framework for these elements, while the actual implementation depends on the laboratory’s field of activity and the techniques used.

General areas the standard addresses

• organizational and management arrangements that support technical competence
• suitability and control of the methods used for testing and calibration
• equipment, personnel, and environmental conditions that affect result reliability
• reporting of results, record keeping, and maintenance of traceability
• routine control of laboratory activities through a quality assurance approach

The value of this standard lies in the common language it creates across different laboratory types. Testing laboratories typically determine properties of a material, product, or sample, while calibration laboratories relate the performance of measuring instruments to reference standards. That distinction matters for both result interpretation and the comparability of laboratories.

This record represents a national edition based on EN ISO/IEC 17025. Its focus is therefore the general requirements for laboratory competence and the shared technical vocabulary of this field; it should not be read as a narrow document for one instrument, one industry, or one specific test method.
