Laboratory of Calibration
What is it ?
Measurement standard
It is a reference, with a value and an uncertainty, to which one compares to establish the accuracy and traceability of its results.
The lower the uncertainty of the standard, the better its quality. We go from the working standard (high uncertainty) to the primary standard (very low uncertainty).
A CALIBRATION
It is the comparison of the values of a measuring instrument to those of a standard, by associating the uncertainties. This comparison allows estimating the bias (accuracy) of the instrument. The values obtained by a calibration are recorded in a "calibration certificate." A calibration can be performed at several points within the measuring range of the equipment to be calibrated. This produces a calibration curve. A calibration curve is used to determine the calibration curve.
