Book Description
This handbook is a both a description of the current practice at the National Institute of Standards and Technology, and a compilation of the theory and lore of gauge block calibration. Most of the chapters are nearly self-contained so that the interested reader can, for example, get information on the cleaning and handling of gauge blocks without having to read the chapters on measurement schemes or process control, etc. This partitioning of the material has led to some unavoidable repetition of material between chapters. The basic structure of the handbook is from the theoretical to the practical. Chapter 1: basic concepts and definitions of length and units; Chapter 2: history of gauge blocks, appropriate definitions and a discussion of pertinent national and international standards; Chapter 3: physical characteristics of gauge blocks, including thermal, mechanical and optical properties; Chapter 4: a description of statistical process control (SPC) and measurement assurance (MA) concepts; and Chapters 5 and 6: details of the mechanical comparisons and interferometric techniques used for gauge block calibrations. Full discussions of the related uncertainties and corrections are included. Finally, the appendices cover in more detail some important topics in metrology and gauge block calibration.

Book Description
Methods And Techniques Of Measurements Are Becoming Increasingly Important In Engineering In Recent Years Laboratory Programmes Have Been Modernized, Sophisticated Electronic Instrumentation Has Been Incorporated Into The Programme And Newer Techniques Have Been Developed. This Book Dwells On The Physical Aspects Of Measurement Techniques. For The Measurement To Be Meaningful, The Nature And Magnitude Of Error Should Be Known. The Book, Thus Begins With Error Analysis And Applications Of Statistical Principles To Attain A Measurement Value As Near The True Value As Possible. The Methods Of Measuring Mechanical Quantities Are Discussed Subsequently, Overing Both The Basic And Derived Quantities. Effort Has Been Made To Present The Subject In S.I. Units. Some Of The Recent Developments Such As Laser-Doppler Techniques, Holography, Have Also Been Included. The Coverage Is Such That The Book Will Be Useful Both Of Graduate And Post-Graduate Students And Will Also Serve As A Constant Reference For Researchers.

Book Description
Methods and Phenomena, 4: Their Applications in Science and Technology: Microweighing in Vacuum and Controlled Environments focuses on the principles, methodologies, and approaches involved in micro mass measurements. The selection first elaborates on introduction and microbalance review, beam microbalance design, construction and operation, and sources of error in microweighing in controlled environments. Discussions focus on Brownian motion, Knudsen forces, gravitational forces, microbalance construction and operation, auxiliary equipment for operation of a vacuum microbalance, undesirable disturbances or forces, calibration techniques, and classification of various types of microbalances. The text then takes a look at physical adsorption studies and chemisorption studies with the vacuum microbalance, simultaneous microgravimetric and residual gas analyzer measurements, and simultaneous measurement of mass change and infrared spectra. Topics include chemisorption results obtained on other solids and silver powders, probing the surface phase, quantitative information from adsorption and desorption, measuring techniques, and examples of physisorption measurements and their evaluation. The manuscript examines unusual applications of the vacuum microbalance and high temperature reaction studies, as well as empirical and theoretical rate laws, permeation of water vapor through plastic membranes, and measurement of permittivity and dielectric loss factor. The selection is a valuable source of data for researchers wanting to explore microweighing in vacuum and controlled environments.
