(ISO: Geneva) -- The International Organization for Standardization and its partner, the International Electrotechnical Commission, have published a new guide on the vocabulary of metrology—the science of measurement and its application.

ISO/IEC Guide 99:2007, “International vocabulary of metrology—Basic and general concepts and associated terms (VIM)”, which is an English-French publication, gives guidance on the concepts and terms used in various approaches to measurement.

Before people can communicate, they need to know and understand the words they wish to use. This is equally true in metrology, where concepts and terms such as “measurement result,” “measurement error,” and “measurement uncertainty” need to be agreed upon if they are to be used in a consistent manner.

Because metrology is in an evolving state concerning what is the best approach (e.g. classical vs. uncertainty), it’s especially important to have an international vocabulary that allows metrologists to communicate clearly about the measurement approach that they are using.
