Measurement-Uncertainty Protocol for Regression-Based Analytical Instruments

摘要

Within the scientific community, measurement uncertainty is a topic of great interest these days. Although it would be nice to have a single protocol that would calculate the uncertainty for all types of measurements made in an analytical chemistry lab, the real world does not lend itself to such an ideal. The members of ASTM Committee D19 on Water have recognized this reality and the group is moving to address a specific portion of the measurement-uncertainty arena. This article summarizes the work that is being done on proposed standard WK13183, Practice for the Estimation of Measurement Uncertainty of a Test Method Involving a Regression-Based Analytical Instrument.
