Abstract

In this paper, a new measurement uncertainty using data evaluation method for proficiency test exercises consisting of combination of a z-test, a zeta test and an uncertainty outlier test is presented. This new method is compared with eight other evaluation methods (both measurement uncertainty using and measurement uncertainty ignoring) in common use and/or recommended by ISO 13528. The data set used to test the evalution methods is real data and consists of the 95Nb results of the NPL Environmental Radioactivity Proficiency Test Exercise 2007. The evaluation of fourteen out of thirty-two results were affected by the choice of method.
