ISO 17025

What is ISO/IEC 17025 Calibration and Test Laboratory Management

ISO/IEC 17025 is a standard which sets out quality management principles relating to laboratories performing calibration and test work. It provides a set of criteria which a laboratory may use as a framework for establishing an effective management system focusing on providing customers with assurance regarding the quality of data provided.

This standard overlaps to some extent with more generic standards such as ISO 9001 but contains much more in the way of technical requirements relating to laboratory operation such as method validation, uncertainty determination, quality controls and reporting of results.

Laboratories may wish to use the requirements of ISO/IEC 17025 to establish their own systems or may seek formal recognition from an independent accreditation agency such as the United Kingdom Accreditation Service (UKAS) who perform accreditation audits directly on laboratories. Such audits contain a substantial amount of technical assessment of methods and associated controls including witness audits of technical activities by specialists which enhances confidence in the assessment and accreditation process.
