ISO/IEC 17025 – Laboratory Accreditation
Introduction
ISO/IEC 17025 is the internationally recognized standard that specifies the general requirements for the competence, impartiality, and consistent operation of testing and calibration laboratories. It applies to all organizations performing laboratory activities, regardless of size or sector, and is widely used to ensure the reliability and accuracy of test and calibration results.
For an accreditation body such as Universal Standards Assessment Forum, ISO/IEC 17025 provides the foundation for assessing laboratories and granting accreditation based on technical competence and effective management systems. Accreditation to this standard demonstrates that a laboratory operates with validated methods, qualified personnel, traceable measurements, and controlled processes—ensuring confidence in results for customers, regulators, and international stakeholders.
ISO/IEC 17025 integrates both management system elements and technical requirements, promoting consistency, transparency, and continual improvement in laboratory operations.
