Traceable Calibration is carried out using equipment that is regularly calibrated by a reference source that can be traced back to a national or international standard.
The calibration certificate produced should show details of the calibration equipment used and its serial number.
If an audit is carried out on a traceable calibration certificate it should be possible to follow the hierarchy of calibration equipment within a organisation and ultimately to an external primary calibration standard which is controlled by a government appointed metrology organisation such as UKAS and NIST.
