摘要：

Very different approaches for the estimation of the uncertainty related to measurement results are found in the literature and in published guidelines. This article analyses and compares them. It is clear that `uncertainty' is not, and should not be, the same in all situations. As a consequence, operational definitions of uncertainty are proposed that take into account the differences in the ways in which truth, uncertainty and error are conceived.
