Our activities


Metrology at LNE is structured around three sectors:

Steering French metrology:
Since 25 January 2005, LNE has been responsible for steering and coordinating metrology activities in France and representing French metrology at international level. It is now on an equal footing with leading national metrology institutes such as PTB (Germany), NPL (UK) or NIST (USA). Assisted by a Metrology Committee of 14 experts, LNE works with three other national metrology laboratories and seven associate laboratories.

Fundamental metrology:
French national reference standards, recognized worldwide, allow manufacturers to align their measuring instruments with the International System of units (SI), as required under the ISO 9000 quality system. LNE maintains and improves these standards in the fields of mechanical, thermal, optical, chemical and electrical quantities.
