ISO 17025 is the primary international standard for the competence of testing and calibration laboratories. Laboratories of all sizes use it to assure their customers they operate competently and generate valid results, thus promoting confidence in their work.

Instrumentation is calibrated in accordance with ISO/IEC 17025 and within approved scope of accreditation. Accredited calibrations provide a certificate of calibration with the accrediting body’s logo on the document, a traceability statement, measurement data and uncertainty for parameter tested during the calibration.

Accredited calibration laboratories are governed by the international standard ISO/IEC 17025 and are regularly audited by a recognized accreditation body like ANAB to test the laboratory’s technical competence and that they follow a proven quality management system. They are guided by quality and integrity in all aspects of their job performance.

Non-accredited calibration laboratories are not required to have any type of formal quality system nor provide measurement traceability data to their customers. They may not follow regulations that govern the technical aspects of the calibration laboratory to ensure that the proper training and methods are applied to the calibration process.
