EURAMET CG-18 – A PRACTICAL APPROACH TO CALIBRATING NON-AUTOMATIC WEIGHING INSTRUMENTS

Klaus Fritsch

Abstract

This paper presents the state-of-the-art calibration strategy for non-automatic weighing instruments (NAWI), based on the recently revised guideline EURAMET cg-18. Besides of the uncertainty at calibration, the document provides advice for the so-called uncertainty of a weighing result that describes the device performance during day-to-day use. The concept of minimum weight was added during a recent revision. The minimum weight is the smallest sample quantity that can be weighed on the device, still adhering to a predefined relative weighing tolerance requirement.
