4.1 Calibration document
The calibration document is the result of the work carried out on the gauge block or set of gauge blocks. It has a technical role, presenting the condition and quality of the set at the time of calibration, but also an official role, as a certificate bearing the COFRAC logo guarantees the user that his equipment is connected to the national standards as required by quality assurance rules.
After each calibration, an analysis and validation of the results must be carried out, to validate the standard's ability or capacity to perform the task assigned to it. This validation must be recorded in the equipment file. This is a requirement of organizational standards such as ISO/CEI 17025, which is the reference standard for calibration and...
