ISO/IEC 17025 is the international standard used to assess the competence of testing and calibration laboratories. Accreditation to ISO/IEC 17025 provides confidence that a laboratory has the systems, processes, and technical capability to deliver reliable and traceable results.
ISO/IEC 17025, General requirements for the competence of testing and calibration laboratories, specifies the management and technical requirements that laboratories must meet to demonstrate competence and produce valid results.
The standard is recognized worldwide and is used by accreditation bodies to evaluate laboratory competence.
Accreditation is an independent evaluation process conducted by an accreditation body. It confirms that a laboratory’s quality management system, technical operations, personnel, equipment, methods, and traceability meet the requirements of ISO/IEC 17025.
Accreditation is not a certification that a specific product, instrument, or result is approved. Instead, it confirms the competence of the laboratory that performs the work.
Accreditation is scope-specific. A laboratory is only accredited for the calibrations, measurement ranges, and capabilities that are listed on its scope of accreditation.
If a calibration is not included in the laboratory’s scope, it is considered a non-accredited service, even if the laboratory is accredited for other capabilities.
Working with an ISO/IEC 17025 accredited laboratory provides several benefits, including greater confidence in measurement results, documented traceability, technical competence, and a strong quality management system.
Accredited calibration is often required by customers, quality systems, and regulatory requirements.
You can verify a laboratory’s accreditation status and scope on the accreditation body’s website. In the United States, ISO/IEC 17025 accredited laboratories are accredited by A2LA (American Association for Laboratory Accreditation).
Always confirm that the calibration capability and range you require are included within the laboratory’s current scope of accreditation.
