To make measurements comparable it is necessary to state the quality of a measurement in terms of the uncertainty of measurement. The ISO/BIPM „Guide to the Expression of Uncertainty in Measurement, usually referred to as the GUM, published in 1993, introduces a unifying method for evaluating and stating measurement uncertainties. This method has been accepted by almost all calibration services in the world and has become a pre-standard in the field of metrology. This paper describes the fundamental aspects of the method which also has entered the EA-4/02 requirement document edited by the European co-operation for Accreditation.
