Traditionally ISO standards concerning acoustical measurement methods include some information about the expected measurement accuracy of the method described. Since a number of years this type of information is treated in much more detail than before. In recently published standards an extensive annex about measurement uncertainty is included. Contradictory to the formerly used terminology the subject is no longer discussed in terms of the Repeatability and the Reproducibility, but in terms of the Standard Uncertainty and the Expanded Uncertainty. Also the Uncertainty Budget was introduced. This terminology is derived from the "Guide to the expression of uncertainty in measurement" (GUM), published by ISO and IEC. The basic principles of the approach according to the GUM will be discussed and the terminology will be clarified. In the second part of the paper the implementation of these principles in the field of building acoustics will be discussed and illustrated with examples of the current Dutch approach.
