Abstract

Because of measurement errors objectively existing, measurement results always deviate from the "true value" of the measurand. Measurement uncertainty, as a quality index characterizing measurement results, attracts more attention worldwide. Its evaluation and expression will help understand measurement results, and promote international technical and commercial communication. According to the International Organization for Standardization ISO/BIPM "Guide to the Expression of Uncertainty in Measurement" - usually referred to as the GUM, this paper deals with the way of evaluation and expression of measurement uncertainties, describes the Procedure for Uncertainty of Measurement MAnagement (PUMA) in the new generation Geometrical Product Specification (GPS). An example of uncertainty evaluation with the PUMA method is given to illustrate the validity of PUMA. Since the concept of uncertainty in the new generation GPS has been expanded beyond just measurement uncertainty, the new way of evaluation and management of uncertainty throughout the whole GPS system remains to be developed.
