The post Q&A with Author of New Edition of ISA Book Measurement Uncertainty first appeared on the ISA Interchange blog site.
EDITOR’S NOTE: As an added bonus, this author Q&A includes a free download of the Uncertainty Analysis Template, a tool for engineers and scientists containing the major equations and summations used in estimating measurement uncertainty, errors and uncertainties that affect results. Scroll down for the template download link.
Q. What prompted you to publish an updated edition of your popular book?
A. The technology of measurement uncertainty analysis has improved over the past several years and these improved methods needed to be included in a new edition. The new book also includes several worked-out uncertainty experiments as well as several new appendices dealing with the specifics of equations and uncertainty analysis methods.
Q. Your book is now in its fifth edition. Why do you think the subject matter of this book continues to be relevant and important as a reference resource??
A. Uncertainty analysis and methods are continuously improving. There’s still a need for a well-organized and presented book for properly analyzing the uncertainty of test and experimental data.
Q. What makes this fifth edition different or more valuable than the fourth edition? What new content has been introduced and what areas have been improved?
A. The fifth edition features new appendices and more detailed examples with each uncertainty analysis and computation clearly described. The new appendices include condensed descriptions of the basics of uncertainty analysis, pinpoint the advantages and disadvantages of several uncertainty models used throughout the world, and provide key equations for uncertainty analysis-all in an easy-to-use format.
The updated book also incorporates:
New and enhanced content has been introduced on the following topics:
There are many ways to conduct an uncertainty analysis. One way is illustrated in the Uncertainty Analysis Template, an Excel spreadsheet in Appendix N of Measurement Uncertainty, Fifth Edition.
The Uncertainty Analysis Template is designed as a starting point for engineers and scientists to use to perform an uncertainty analysis. It contains the major equations and summations used in estimating measurement uncertainty, errors and uncertainties that affect results, ASME random and systematic categories, and ISO pedigree categories Type A (from statistical analysis) and Type B (obtained other ways).
