DIN EN ISO/IEC 17025

ISO 17025 (officially: DIN EN ISO/IEC 17025) defines the general requirements for the competence of testing and calibration laboratories. It is the internationally recognized standard for laboratory quality management and technical competence.

Scope and Purpose

The standard ensures accuracy, traceability, and impartiality in laboratory results. It applies to all organizations conducting testing, calibration, or sampling, regardless of their size or field.

Structure

The current version, ISO 17025:2017, is structured into eight clauses:

1. Scope

2. Normative References

3. Terms and Definitions

4. General Requirements – impartiality and confidentiality

5. Structural Requirements – organizational structure and responsibilities

6. Resource Requirements – personnel, facilities, equipment, and traceability

7. Process Requirements – method validation, measurement uncertainty, result reporting

8. Management System Requirements – document control, corrective actions, internal audits

Accreditation

Accreditation to ISO 17025 demonstrates that a laboratory operates competently and generates valid results. In Germany, this is typically granted by DAkkS (Deutsche Akkreditierungsstelle).

Accreditation enhances credibility and ensures that test results are recognized across international markets and regulatory systems.

Relevance for Product Testing

Compliance with ISO 17025 is essential for laboratories involved in:

• EMC, RF, and SAR testing

• Environmental simulation

• Electrical safety

• Calibration services

Test reports from ISO 17025-accredited labs are widely accepted by regulatory authorities and market access bodies worldwide.
