2015年6月22日 · NIST supports accurate and compatible measurements by certifying and providing more than 1,200 Standard Reference Materials® with well-characterized composition or properties, or both. These materials are used to perform instrument calibrations in units as part of overall quality assurance programs, to verify the accuracy of specific ...

2021年6月15日 · How measurement standardization helps clarify technical details and foster international collaborations and technological innovation.

2023年4月4日 · The first stage in determining what motivates people to utilize the most up-to-date standardized measurement approach in civil engineering construction projects is to develop a research model of the variables and to explain the connection between the driver and strategy factors on standard adoption.

2022年5月2日 · Measurement and standards challenges — and opportunities — abound as we head further into the 21st century. Let’s look at two examples. The first could revolutionize drug design — and make those drugs more available to the wider public.

This open access book proposes a conceptual framework for understanding measurement across a broad range of scientific fields and areas of application, such as physics, engineering, education, and psychology.

2024年4月26日 · They represent certain units of measurement to the closest possible accuracy that production and measurement technology allow. International standards are periodically checked and evaluated by absolute measurements in terms of the fundamental units. The table below illustrates basic SI units, Quantities and Symbols:

1999年10月7日 · The NIST ITL approach uses the principles of measurement science, adapting them to measuring a software product's conformance to particular standards, as well as its performance and dependability. ITL also works with industry to establish credible, cost-effective test suites to demonstrate software conformance to particular standards.

This book explores the modern role of measurement science for both the technically most advanced applications and in everyday and will help readers gain the necessary skills to specialize their knowledge for a specific field in measurement.
