– The ACCREDITED test provides a CERTIFICATE of Calibration, which is an official document recognised by all international metrology organisations. (EA – IAF – ILAC).
This certificate can only be issued by an accredited laboratory under control of Accredia (Italian organisation for Accreditation), which thoroughly checks:
- The procedure and the working mode
- The instruments
- The training of the operators
These checks confirm the competence of the Laboratory and the reliability of the tests performed. However, this procedure generates costs.
– Non-accredited Calibration gives a Calibration REPORT, which can be issued by a Laboratory not fulfilling the above criteria. In fact, almost anyone can conduct non-accredited Calibrations, but certified gauges must be used (load cells, weights, gauges…) Non-accredited Calibration can be carried out thoroughly and be reliable, but this depends on the Laboratory that does the job and the control the customer can have on the operation.
There are 2 major issues:
- The Certificate of Calibration is internationally recognized.
- An Accredited Laboratory is a proof of reliability.
