Intrinsic uncertainty in measurement: an interpretation model for metrological standards

Description

The role of uncertainty in the acquisition and processing of experimental data has fundamental relevance, both theoretical and practical, for the metrological assessment of technology. The restitution procedures have been based, traditionally, on the 'error theory' and exploit a mainly statistical formulation in order to approach the 'true value'. In the note the alternative framework, recently proposed by the Italian Standard (UNI 4546, 1984), based on the concept of 'intrinsic uncertainty', is recalled and the related restitution procedures are discussed, with explicit reference to a probabilistic formulation. © 1990.
