QUALITY EVALUATION OF MEASUREMENT INSTRUMENTS

L. Wisweh, M. Sandau

Abstract

At present, no standardized procedures exist for regulating the process of calculating the certainty of measurement results. Taking geometric measurement activities in the production engineering environment as an example, the presentation indicates methods of establishing mathematical parameters for statistical assessment purposes as a means of ensuring that results can be reliably compared.<BR />When it comes to evaluating the ability of measuring instruments to permit quality standards to be reliably assessed, measuring uncertainty is an important factor. Moreover, even describing the capabilities of measuring instruments is gaining in importance. In order to consider these predominantly statistical descriptive variables with a sufficient degree of reliability, however a standardized or comparable definition is required.<BR />The first part deals with measuring uncertainties. The second part of the contribution indicates problem areas associated with measuring instrument capabilities, together with possible solutions.
