French metrology

French metrology

In 2005 the French government passed a decree entrusting LNE with overall responsibility for all French metrology. Renamed the Laboratoire National de Métrologie et d'Essais, LNE took over from the Bureau National de Métrologie, which had performed this function since 1969.

Now on an equal footing with other leading national metrology institutes such as PTB (Germany) NPL (UK) and NIST (USA), LNE will represents France in the work carried out by the International Weights and Measures Bureau (BIPM). The Laboratory has set up a Metrology Committee to oversee decisions and long-term strategy. Comprising 14 leading scientists and metrologists and representatives of the French Ministries of Industry and Research, the Metrology Committee steers research work in priority fields, aligns investment with research programmes and creates mixed units of researchers where possible.

French metrology laboratories

LNE possesses extensive scientific and technical resources to meet requirements in a wide range of SI reference standards. The fields it covers are electricity and magnetism, dimension, mass and related quantities (pressure, force, torque, acoustics, accelerometry), amount of substance, radiometry-photometry, temperature and thermal quantities. The Laboratory relies on the expertise of almost 250 metrology engineers and technicians, over half of whom are involved in scientific and technological research activities.

Four national metrology laboratories

For some spheres of measurement, LNE calls on other respected scientific bodies, in particular three other national metrology laboratories:

Working together for a changing world, a key priority
for France's metrology network.

Organization, teams, projects and perspectives
of the French metrology network.

LNE-INM (National Metrology Institute),
part of the Arts et Métiers education and research institution (CNAM), which works in the fields of dimension, mass and related quantities, radiometry-photometry, temperature and thermal quantities
LNE-LNHB (Henri Becquerel National Laboratory),
part of the Atomic Energy Commission, which is responsible for developing reference standards in the field of ionizing radiation
LNE-SYRTE (Time-Space Reference Systems),
part of the Paris Observatory, which is responsible for developing reference standards in the time-frequency field.

Seven associate laboratories

LNE also relies on six associate laboratories for work in highly specific fields:

CETIAT (Technical Centre for Aeraulics and Thermics Industries)
for hygrometry, liquid flow measurement and anemometry
ENSAM-Paris (Arts et Métiers engineering school, Paris)
for dynamic pressure
LTFB (Laboratoire Temps Fréquence de Besançon)
for time-frequency
IRSN (Radiation Protection and Nuclear Safety Institute)
for neutron dosimetry
LADG (Gas Flow Measurement Associate Laboratory)
for gas flow measurement
TRAPIL (Petroleum Transport by Pipeline)
for liquid hydrocarbon flow measurement.

LNE’s responsibilities as a reference body

LNE's main responsibilities cover:

defining and coordinating the work
of the national metrology laboratories and their long-term study and research programmes
distributing French metrology assignments among the laboratories,
in order to ensure that users have access to the appropriate metrological references for their needs
providing funding or technical support
for studies and research in the field of metrology
initiating key studies and research
in the fields of fundamental and applied metrology
representing France
at the General Conference on Weights and Measures (CGPM) and in European and international organizations in the fields of fundamental and applied metrology
publishing information
on developments in metrology
ensuring all measurements are traceable to national standards
and taking appropriate steps to obtain international recognition.
