5. Dimensional metrology calibration laboratory
5.1 Space planning
Instrument indications are very often a function of environmental conditions and the effect of influencing variables such as temperature, humidity, etc. It is therefore necessary to define reference conditions under which calibration is carried out. It is therefore necessary to define the reference conditions under which calibration is carried out. These reference conditions are specified in normative texts or are the subject of agreements.
Stability of environmental conditions and influence quantities is essential during calibration. Permissible fluctuations are determined according to the desired calibration uncertainty.
When the instrument is used in environmental conditions that differ from the reference conditions,...

National metrology laboratories
In 2005, a joint decree by the French Ministries of Industry and Research dissolved the Bureau national de métrologie and transferred the task of overseeing metrology to the LNE, which changed its name to Laboratoire national de métrologie et d'essais, but kept its acronym LNE. http://www.lne.fr
Alongside LNE, 3 other...
