Abstract

The paper analyzes the concept of accuracy, and the related ones of trueness and precision, as aimed at characterizing the behavior of measurement processes, and highlights how such concepts, as currently defined by some relevant standards, should be reformulated to guarantee their consistency. Finally, some preliminary suggestions are proposed to this goal.
