ISO 17025 Calibration Certificate

The Calibration Certificate

A Calibration Certificate is a document that only an ISO 17025 accredited Calibration Centre can issue.

The Calibration Certificate contains all information relating to the instrument, such as: date of calibration and serial number, measurement result, uncertainties, reference standards, instrumentation used, environmental conditions during measurements.

All procedures related to the issuance of the Certificate comply with the requirements of UNI CEI EN ISO/IEC 17025:2018 and ACCREDIA, the sole national accreditation body appointed by the Italian government, guarantees through regular and periodic inspections.

By presenting a Calibration Certificate together with an instrument, the customer is relieved of any obligation to demonstrate to third parties that calibrations have been carried out in accordance with the standards and guarantees the traceability of the results contained therein. In addition, thanks to mutual recognition agreements, this certificate is officially valid in countries belonging to EA (European Cooperation for Accreditation) and ILAC (International Laboratory Accreditation Cooperation).


ACCREDIA is the body designated by the Italian government to certify the competence, independence and impartiality of bodies and laboratories that verify the conformity of goods and services to standards. ACCREDIA is a member of the worldwide and European accreditation networks EA-IAF-ILAC and is a signatory of the relevant international mutual recognition agreements.


ILAC stands for “International Laboratory Accreditation Cooperation”. Through ILAC MRA – Mutual Recognition Arrangement – it is ensured that calibration certificates are recognised by all signatory members, regardless of country.
