Calibration is a comparison between measurements – one of known magnitude or correctness made or set with one device and another measurement made in a similar way as possible with a second device.

To improve the quality of the calibration and have the results accepted by outside organizations it is desirable for the calibration and subsequent measurements to be “traceable” to the internationally defined measurements units.

Establishing traceability is accomplished by a formal comparison to a standard which is directly or indirectly related to national standards (KEBS in the KENYA), international standards, or certified reference materials.

Quality Management Systems call for an effective metrology system which includes formal, periodic and documented calibration of all measuring instruments. ISO 9000 and ISO 17025 sets of standards require that these traceable actions are to a high level and set out how they can be quantified.
