Stability Tests in the Process of Organization of Interlaboratory Comparison

Success in programs of interlaboratory comparisons is based on two basic pillars. In addition to the inseparable share laboratory and quality activities performed, organized program comparison also affects final success. Organizing tests a time consuming process. It includes several important stages that precede laboratory's participation itself. One most selection an object suitable for purpose comparative measurements. criteria selecting item its stability. The article focuses basis ILC, causes unsuccessful results, areas where stability test required not, one possible approaches checking measuring instrument. proposed approach defined by measurement model, described methodological steps was applied practice, results were evaluated analysed discussion. conclusion, it can be stated particularly obtain relatively large amount data automating collection, as application statistical approaches. Even with this approach, cost-effectiveness must not forgotten, impact price ILC. situation therefore requires search optimal solutions terms degree risk cost tests.
