TS EN 45001

TS EN 45001 is a withdrawn accreditation standard focused on the general criteria used to assess the technical competence of testing laboratories. Based on the title and scope information, it brings together the core organizational and technical expectations for operating testing laboratories across sectors, and it also refers to calibration laboratories within that broader framework. Standards of this kind establish a common basis for understanding the reliability, traceability, and consistency expected from laboratory services.

What technical competence means in a testing laboratory

In general technical terms, competence covers qualified personnel, appropriate test methods, control of measuring and test equipment, orderly records, and the ability to produce repeatable results. Testing laboratories work to measure or verify properties of materials, products, or systems; for that reason, laboratory organization and technical practice cannot be separated. General accreditation criteria therefore address not only how tests are performed, but also whether the laboratory has the structure needed to perform them reliably.

The document’s practical scope

• It applies to testing laboratories without sector limitation.
• Calibration laboratories are explicitly included in the scope text.
• Its purpose is to define common criteria for technical competence.
• It is a TSE edition based on EN 45001:1989.
• It is withdrawn, so it is mainly of historical and reference value.

In laboratory standards, test method control, measurement uncertainty, equipment suitability, and reporting practices are closely connected. The title and scope of this standard indicate that its main concern is the overall operating competence of the laboratory rather than a single test procedure. In that sense, it serves as a foundational reference linking laboratory management with technical execution.
