Abstract

An alternative procedure for the evaluation of certification study data is proposed. The aim of this proposal is to incorporate the concepts and methods proposed by the “Guide to the Expression of Uncertainty in Measurement” (ISO 1993, 1995) into the certification of reference materials. The proposed procedures, which are well established in metrology, basically use the technique of inverse-variance weighted means.
