Beskrivning

Metrology is an integral part of the structure of today’s world: navigation and telecommunications require highly accurate time and frequency standards; human health and safety relies on authoritative measurements in diagnosis and treatment, as does food production and trade; global climate studies also depend on reliable and consistent data. Moreover, international trade practices increasingly require institutions to display demonstrated conformity to written standards and specifications. As such, having relevant and reliable results of measurements and tests in compliance with mutually recognised standards can be a technical, commercial and statutory necessity for a company. This book, the results of a working group from the French College of Metrology and featuring chapters written by a range of experts from a variety of European countries, gives a comprehensive and international treatment of the subject. Academics involved in metrology as well as people involved in the metrology capacities of companies and institutions will find this book of great interest.
