Evaluation by Interlaboratory Test Results

156 Pages, PDF
Determination of measurement uncertainty is normally quite laborious, but this book shows how the available interlaboratory test data for plastics can be used to calculate measurement uncertainty much more simply. It contains many interlaboratory test results in the fields of thermoanalysis, molar mass determination, and quantitative analysis of the composition of material, presented in tables and graphical charts, discussed in the text, and elaborated by practical examples.
In addition to the evaluation by means of the presented data (top-down approach), the relationship to the bottom-up approach specified in the Guide to the Expression of Uncertainty in Measurement (GUM) is explained based on an example. Further sections deal with sampling, and the issue of whether or not the difference between analytical results is significant.

Dr. Bruno Wampfler (retired) was Head of Process and Product Optimization at Empa St. Gallen, Switzerland. He was initiator of the Eureka project “Uncertainty Manager”.
Dr. Samuel Affolter is Professor for Chemistry and Plastics Technology at the NTB (Interstaatliche Hochschule für Technik, Buchs), Switzerland. He leads the polymer team in the Institute for Micro- and Nanotechnology (MNT), focusing on polymer analysis and functionalized materials.
Dr. Axel Ritter is a chemist at Intracosmed AG, Urnäsch, Switzerland, where he is responsible for quality assurance and regulatory issues.
Dr. Manfred Schmid studied chemistry in Bayreuth, Germany, and received his doctorate in polymer chemistry. Until 1997 he was employed as a chemist in polyamide research at EMS-Chemie. Subsequently, Mr. Schmid was project manager in the field of plastics analysis/biopolymers at EMPA. Since 2008 he has been head of research and development for SLS at Inspire AG, irpd, Switzerland.
