INTERCOMPARISON REFERENCE FUNCTIONS AND DATA CORRELATION STRUCTURE

    Abstract:

    Interlaboratory comparisons (IC) are key instruments for ensuring the performance and reliability of, and the comparability between, the participating facilities. Interlaboratory comparisons are also a mighty tool for assessing reference values to measurement standards or reference materials. In modern measurement and testing, determination of functionally related properties of the reference object, or of the performance characteristics of an instrument within a certain measuring range is common practice. Intercomparisons in these areas require the calculation of IC reference functions (RF) instead of series of isolated IC reference values. A number of decisions have to be made concerning the appropriate type of the ICRF, a regression technique which enables accounting for the full uncertainty/correlation structure, and appropriate result assessment. The paper discusses a particular approach which is exemplified for an IC in equipment qualification using a (travelling) transfer instrument for the comparison of an on-site measuring instrument with a reference standard.
