The uncertainty of measurement results is drawing attention of managers, metrologists and customers. The accuracy of measurements affects all of us in trade, commerce, safety, health care environmental protection and more. The quality of these measurements are regulated by a variety of government agencies. Measurement also plays an important role in manufacturing and service organizations. Use this book to learn more about metrology and the need for reliable measurements. You can also learn about measurement system and quality of measurement systems, objectives and methods. Statistical techniques in metrology are also explained. Examples of measurement data and random variables, probability density functions, sampling distribution, statistical estimation degrees of freedom and regression are included.

An entire chapter is devoted to measurement errors. The book goes in-depth into explaining national and international measurement systems and standards, and includes a complete chapter on calibration and measurement trace ability. Measurement Uncertainty will show how to evaluate various uncertainties in measurements using several approaches including international consensus. Calibration laboratories can look specifically at the chapter on that profession to guide them in their measurement improvements. Kimothi also looks at specific industries and their measurement capabilities and includes examples of R&R studies

A great resource for the CQE, CQT, CCT, and CSSBB certification exams!

  • "This book deals with the science of Metrology in the most comprehensive manner I have seen so far. Topics include the nature of measurements and measuring systems; statistical methods that apply to measurement; traceability; measurement assurance; and a very useful and understandable treatment of measurement uncertainty. The information is presented from the viewpoint of the needs of a calibration or testing laboratory. A theme throughout the book is the requirements of ISO/IEC 17025:1999 and other international standards. However, all of the information is useful knowledge and/or good practice for any calibration or testing organization."
