Laboratoire national de métrologie et d'essais
The Laboratoire national de métrologie et d'essais (National Laboratory of Metrology and Testing) is a French reference laboratory responsible for carrying out measurement and testing products of all kinds for their certification for placing them on the market. It also coordinates metrology activities in France. It was previously known as the Laboratoire national d'essais (LNE), and still uses those initials.
Originally established in 1901, it is now a state-owned enterprise, and operates as an Établissement public à caractère industriel et commercial, a French type of state-controlled entity of an industrial or commercial nature.
Its headquarters is located in the 15th arrondissement of Paris.
