What is ISO/IEC Guide 99 and How to Access it for Free?
ISO/IEC Guide 99 is a document that provides a set of definitions and associated terms for a system of basic and general concepts used in metrology, the science of measurement. It also includes concept diagrams to demonstrate the relations among the concepts. The document is intended to facilitate communication and promote common understanding of metrology among various fields of science, technology, industry and society.

The document was first published in 2007 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), as a replacement of the second edition of the International Vocabulary of Basic and General Terms in Metrology (VIM). It is equivalent to the third edition of the VIM. The document is also known as the International Vocabulary of Metrology (IVM).
ISO/IEC Guide 99 covers concepts such as quantities and units, measurement, devices for measurement, properties of measuring devices, measurement standards and reference materials. It also provides guidance on how to use the terms and definitions consistently and correctly. The document is not intended to prescribe how terms should be formed or which terms should be preferred.
ISO/IEC Guide 99 is available in English and French versions, as well as in Russian translation. It can be accessed online for free through the ISO Online Browsing Platform (OBP) [^1^], which allows users to view and search the document interactively. Users can also download a PDF version of the document for free from various websites [^2^] [^4^], but they should be aware that some of the elements of the document may be subject to patent rights and that ISO/IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC Guide 99 is a useful resource for anyone who is involved or interested in metrology and its applications. It can help to improve the clarity and accuracy of communication and documentation related to measurement concepts and processes.
Metrology has many applications in various fields of science, technology, industry and society. Some examples of metrology applications are:
Time and frequency metrology, which deals with the measurement of time intervals and frequencies of physical phenomena, such as atomic clocks, global navigation satellite systems (GNSS), telecommunications and radio astronomy. [^1^]
Optical metrology, which uses light and optical instruments to measure physical quantities, such as length, angle, surface shape, refractive index and optical power. Optical metrology includes techniques such as interferometry, holography, microscopy and spectroscopy. [^2^]
Nano-metrology, which focuses on the measurement of nanoscale objects and phenomena, such as nanoparticles, nanomaterials, nanodevices and nanofabrication. Nano-metrology requires high-resolution and high-precision instruments and methods to overcome the challenges of nanoscale measurements. [^2^]
Environmental metrology, which involves the measurement of environmental parameters and pollutants, such as temperature, humidity, pressure, wind speed, air quality, water quality and radiation. Environmental metrology supports the monitoring and assessment of environmental conditions and impacts. [^2^]
Biomedical metrology, which applies measurement principles and techniques to biomedical sciences and engineering, such as biotechnology, biochemistry, molecular biology, genetics and medicine. Biomedical metrology includes measurements of biological entities and processes, such as cells, tissues, organs, biomolecules and biochemical reactions. [^2^]
Legal metrology, which covers the regulation and statutory requirements for measuring instruments and methods of measurement used for trade, health, safety and environmental protection purposes. Legal metrology ensures the accuracy and reliability of measurements that affect the public interest. [^2^]
Metrology plays a vital role in advancing science and technology, improving industrial productivity and quality, enhancing consumer protection and confidence, facilitating international trade and cooperation, and contributing to social welfare and sustainable development. Metrology is therefore essential for the progress and prosperity of humanity. e0e6b7cb5c
