ISO 17025 is the international standard for testing and calibration laboratories. Unlike most management system standards, it assesses technical competence as well as management processes, covering personnel, equipment, methods and the validity of results themselves.
Certification / Accreditation
ISO 17025 Testing and calibration laboratories

How Q! supports certification
Technical competence, not just paperwork
Because this standard combines management system requirements with technical competence, we work closely with laboratory personnel on the technical detail: method validation, measurement uncertainty and traceability, not just documentation. If you already hold ISO 9001, we help you use Option B to streamline the management system requirements rather than duplicating effort.
