SAMA Italia Srl® offers laboratory test reports and/or ACCREDIA calibration certificates on its own product range or on equipment already possessed by your company. These services aim to grant customer satisfaction and to rationalize the number of suppliers. In the text below you can find the main differences between ACCREDIA calibration certificates and laboratory test reports.


 ACCREDIA CALIBRATION CERTIFICATE: it’s a document that can be edited only by a metrological laboratory licensed by ACCREDIA. This certificate it’s officially recognized in Italy and even by all European countries adherent to EA (European Cooperation for Accreditation). An ACCREDIA calibration certificate testifies that an instrument has been calibrated accordingly to procedures mutually acknowledged by the primary institutes of competence.

ACCREDIA certificates relieve their holder by any obligation to demonstrate to third parties that the calibrations have been performed as provided by the quality system standard for metrological laboratories (see UNI CEI EN ISO/IEC 17025) and according to procedures approved by ACCREDIA.

Instruments and reference samples certified by laboratories acknowledged by ACCREDIA are usually employed as “primary reference standards” (e.g. gauge blocks) in order to calibrate and control other equipment.



LABORATORY TEST REPORT WITH REFERENCE TO NATIONAL ACKNOWLEDGED SAMPLES (LTR) (UNI EN ISO 10012:2004): it’s a document edited by metrological laboratories that insures that the test has been made with reference to national acknowledged samples, without being licensed by the institution in charge. Generally speaking this type of documents is required to perform internal controls on measuring equipment employed for field measurement (e.g. pressure switches, multimeters, temperature meters, pressure gauges, calipers, dial indicators, micrometers etc.)

The technical worthiness of these documents it’s based on the laboratory’s qualification, on the operator’s expertise and by the metrological procedures employed. The customer has full right to attest such features through on-site inspections.
